SYSTEMATIC NAME
IUBMB Comments
CoA-[4'-phosphopantetheine]:apo-[acyl-carrier protein] 4'-pantetheinephosphotransferase
Requires Mg2+. All polyketide synthases, fatty-acid synthases and non-ribosomal peptide synthases require post-translational modification of their constituent acyl-carrier-protein (ACP) domains to become catalytically active. The inactive apo-proteins are converted into their active holo-forms by transfer of the 4'-phosphopantetheinyl moiety of CoA to the sidechain hydroxy group of a conserved serine residue in each ACP domain [3]. The enzyme from human can activate both the ACP domain of the human cytosolic multifunctional fatty acid synthase and that associated with human mitochondria as well as peptidyl-carrier and acyl-carrier-proteins from prokaryotes [6]. Removal of the 4-phosphopantetheinyl moiety from holo-ACP is carried out by EC 3.1.4.14, [acyl-carrier-protein] phosphodiesterase.

PPTases can be classified into three groups according to their structures. A group I PPTase, also named as an ACPS-type PPTase, consists of three identical peptide subunits with about 120 amino acid residues in each subunit. A group II PPTase, also named as a Sfp-type PPTase, consists of one peptide which is about twice the size of one group I PPTase subunit. A group III PPTase exists as a domain of a FAS or a PKS. FKPPT1, FKPPT2, FKPPT3, FKPPT4 contains three conserved motifs, PRWP, GID and FSAKESVYK, found in the Sfp-type PPTase motifs P1, P2 and P3, while FKACPS contains just last two conserved motifs found in ACPS-type PPTase.

phosphopantetheinyl transferases (PPTases) are essential for cell viability across all three domains of life: bacteria, archaea and eukaryota. Holo-ACP synthase (AcpS) is the archetypical enzyme of the first family of PPTases recognized. Surfactin phosphopantetheinyl transferase (Sfp) represents the second family of PPTases. The third family of PPTases are translationally fused C-terminal transferases residing in the megasynthases as one of several catalytic domains acting in type I yeast and fungal FAS megasynthases. This third family of PPTases post-translationally modify apo-ACPs prior to assembly of the megasynthases

PPTases posttranslationally modify modular and iterative synthases acting in a processive fashion, namely fatty acid synthases, polyketide synthases, and non-ribosomal peptide syntethases. The central component of these chain elongating synthases is non-catalytic and either a translationally linked domain of a larger polypeptide chain or an independently translated protein.

The CP tethers the growing intermediates on a 4'-phosphopantetheine (PPant) arm of 20 A through a reactive thioester linkage. PPants are thought of as prosthetic arms on which all substrates and intermediates of these pathways are covalently yet transiently held during the orderly progression of enzymatic modifications to the extending chain.

The central component of these chain elongating synthases is non-catalytic and either a translationally linked domain of a larger polypeptide chain or an independently translated protein. Regardless, this protein component is referred to as a carrier protein, or alternatively a thiolation domain. The CP tethers the growing intermediates on a 4'-phosphopantetheine (PPant) arm of 20 A through a reactive thioester linkage. PPants are thought of as prosthetic arms on which all substrates and intermediates of these pathways are covalently yet transiently held during the orderly progression of enzymatic modifications to the extending chain. PPTases mediate the transfer and covalent attachment of PPant arms from coenzyme A (CoA) to conserved serine residues of the carrier protein domain through phosphoester bonds. These essential posttranslation protein modifications convert inactive apo-synthases to active holo-synthases. Mechanistically distinct classes of enzymes have been identified that require PPant arms for biosynthetic catalysis. These include enzymes involved in the biosynthesis of lipid A, D-alanyllipoteichoic acid, lipo-chitin nodulation factor, beta-alanine-dopamine conjugates, carboxylic acid reductions, and dehydrogenation of alpha-aminoadipate semialdehyde (lysine biosynthesis) and 10-formyl-tetrahydrofolate.

4'-phosphopantetheinyl transferase post-translationally modifies carrier proteins with a phosphopantetheine moiety, an essential reaction. In Mycobacteria, the Sfp-type PPTase activates pathways necessary for the biosynthesis of cell wall components and small molecule virulence factors; the enzyme PptT is the PPTase for the mycobactin synthase. Siderophores in Mycobacterium tuberculosis are peptide-based and fall into two categories, the water-soluble exochelins and the membrane-associated mycobactins. siderophore or other natural product production is regulated by the activity of the PPTase. PptT is necessary for in vitro growth of mycobacteria, but mycobacteria require enzymes in vitro that are not always required in vivo. PPTases posttranslationally modify modular and iterative synthases acting in a processive fashion, namely fatty acid synthases, polyketide synthases, and non-ribosomal peptide syntethases. The central component of these chain elongating synthases is non-catalytic and either a translationally linked domain of a larger polypeptide chain or an independently translated protein.

Essential enzymatic role of PPTases in general fatty acid biosynthesis. AcpSs are primarily used for post-translational modification and activation of the carrier proteins of FASs (primary metabolism) across a diversity of organisms making them the most commonly found PPTase. Mycolic acid, mycobactin, polyketide-derived lipids, fatty acids, siderophores and some yet to be discovered natural products all depend on PPTase activity for biosynthesis
-
physiological function
-
the enzyme is essential. Two siderophores, pyoverdin and pyochelin, are produced by NRPSs and associated with the virulence of these bacteria. Pyoverdine biosynthesis requires phoshopantetheinylation of PvdD, PvdI and PvdJ and pyochelin biosynthesis requires activation of PchE and PchF. PaPcpS acts on FAS, PKS and NRPS acyl carrier proteins, but the PPTase is optimized for primary metabolism, since its activity drops 30-fold for ACPs or PCPs from secondary metabolism in vitro
-
physiological function
-
the biosyntheses of the red pigment prodigiosin and the surfactant serrawettin W1 in Serratia marcescens depend on the presence of the PPTase PswP. Serratia species appear to employ two PPTases, one to activate the PCP of PigG and one to activate the ACPs of PigH. Besides PswP, PigL also is a PPTase. Two Sfp/EntD-type PPTases are identified, encoded by genes SMA4147 and SMA2452
-
physiological function
-
overexpression of the enzyme not only increases the natamycin production by about 40% but also accelerates productions of both natamycin and the spore pigment; phosphopantetheinyl transferases play an essential role in the biosyntheses of fatty acids, polyketides, and nonribosomal peptides

Streptomyces coelicolor contains 25 biosynthetic secondary metabolite clusters that produce natural products, including actinorhodin, coelichelin, coelibactin, TW95a, EPA, methylenomycin (encoded on a giant linear plasmid), prodiginines and the antibiotic CDA. All of these natural products are produced by synthases that require phoshopantetheinylation by an AcpS-type PPTase, which shows a high level of permissiveness for CoA substrates as well as carrier proteins. For example, type I mammalian FAS, type I fungal PKS, and several type II bacterial ACPs are efficiently phosphopantetheinylated. The genome of Streptomyces coelicolor contains two other PPTases: RedU, which is a dedicated PPTase for undecylprodigiosin biosynthesis, and SCO6673 required for CDA biosynthesis. Both RedU and SCO6673 have specific carrier protein targets, whereas ScAcpS shows broad activity. The crystal structure of ScAcpS shows the structural basis for relaxed substrate selection

phosphopantetheinyl transferases (PPTases) catalyze the phosphopantetheinylation of acyl carrier proteins (ACPs) in polyketide synthases (PKSs), peptidyl carrier proteins (PCPs) in nonribosomal peptide synthetases (NRPSs), and ACPs in fatty acid synthases (FASs) from inactive apo-forms into active holo-form. PPTases are essential to both primary metabolisms and secondary metabolisms. Phosphopantetheinylation of the ACP/PCP is involved in FK506 biosynthesis, FK506 (tacrolimus) is a clinical immunosuppressant widely used after allogeneic kidney, liver, and heart transplantations; phosphopantetheinyl transferases (PPTases) catalyze the phosphopantetheinylation of acyl carrier proteins (ACPs) in polyketide synthases (PKSs), peptidyl carrier proteins (PCPs) in nonribosomal peptide synthetases (NRPSs), and ACPs in fatty acid synthases (FASs) from inactive apo-forms into active holo-form.

some Vibrio anguillarum strains produce the siderophore vanchrobactin utilizing the NRPS VabF. VabD is the dedicated PPTase used for 4'-phosphopantetheinylation of VabF. Vibrio anguillarum strains also contain a second, more dominant, siderophore anguibactin, located on the pJM1 plasmid. Anguibactin is also synthesized by an NRPS and requires the PPTase AngD. Both VabD and AngD can complement one another, but since anguibactin is the more potent siderophore, some strains have lost the vanchrobactin biosynthesis pathway

the enzyme activates the siderophore petrobactin. The synthase-encoding cluster contains a stand-alone PCP domain, AsbD, which is phosphopantetheinylated by a PPTase. There is no PPTase present in the gene cluster itself and it is suggested that BA2375, an EntD homologue present in the enterobactin gene cluster, serves as the PPTase that installs the 4'-phosphopantetheinyl arm on AsbD. Holo-AsbD is loaded with 3,4-dihydroxybenzoic acid by AsbC and this AsbD conjugate functions as the substrate for AsbE. AsbE, together with the stand-alone synthases AsbA and AsbB, catalyze the formation of petrobactin

PPTases posttranslationally modify modular and iterative synthases acting in a processive fashion, namely fatty acid synthases, polyketide synthases, and non-ribosomal peptide syntethases. The central component of these chain elongating synthases is non-catalytic and either a translationally linked domain of a larger polypeptide chain or an independently translated protein. Regardless, this protein component is referred to as a carrier protein, or alternatively a thiolation domain. The CP tethers the growing intermediates on a 4'-phosphopantetheine (PPant) arm of 20 A through a reactive thioester linkage. PPants are thought of as prosthetic arms on which all substrates and intermediates of these pathways are covalently yet transiently held during the orderly progression of enzymatic modifications to the extending chain. PPTases mediate the transfer and covalent attachment of PPant arms from coenzyme A (CoA) to conserved serine residues of the carrier protein domain through phosphoester bonds. These essential posttranslation protein modifications convert inactive apo-synthases to active holo-synthases. Sfp is the PPTase necessary for installing PPant on the PCP of surfactin synthase

The central component of these chain elongating synthases is non-catalytic and either a translationally linked domain of a larger polypeptide chain or an independently translated protein. Regardless, this protein component is referred to as a carrier protein, or alternatively a thiolation domain. The CP tethers the growing intermediates on a 4'-phosphopantetheine (PPant) arm of 20 A through a reactive thioester linkage. PPants are thought of as prosthetic arms on which all substrates and intermediates of these pathways are covalently yet transiently held during the orderly progression of enzymatic modifications to the extending chain. PPTases mediate the transfer and covalent attachment of PPant arms from coenzyme A (CoA) to conserved serine residues of the carrier protein domain through phosphoester bonds. These essential posttranslation protein modifications convert inactive apo-synthases to active holo-synthases

the enzyme activates the siderophore petrobactin. The synthase-encoding cluster contains a stand-alone PCP domain, AsbD, which is phosphopantetheinylated by a PPTase. There is no PPTase present in the gene cluster itself and it is suggested that BA2375, an EntD homologue present in the enterobactin gene cluster, serves as the PPTase that installs the 4'-phosphopantetheinyl arm on AsbD. Holo-AsbD is loaded with 3,4-dihydroxybenzoic acid by AsbC and this AsbD conjugate functions as the substrate for AsbE. AsbE, together with the stand-alone synthases AsbA and AsbB, catalyze the formation of petrobactin

PPTases posttranslationally modify modular and iterative synthases acting in a processive fashion, namely fatty acid synthases, polyketide synthases, and non-ribosomal peptide syntethases. The central component of these chain elongating synthases is non-catalytic and either a translationally linked domain of a larger polypeptide chain or an independently translated protein. Regardless, this protein component is referred to as a carrier protein, or alternatively a thiolation domain. The CP tethers the growing intermediates on a 4'-phosphopantetheine (PPant) arm of 20 A through a reactive thioester linkage. PPants are thought of as prosthetic arms on which all substrates and intermediates of these pathways are covalently yet transiently held during the orderly progression of enzymatic modifications to the extending chain. PPTases mediate the transfer and covalent attachment of PPant arms from coenzyme A (CoA) to conserved serine residues of the carrier protein domain through phosphoester bonds. These essential posttranslation protein modifications convert inactive apo-synthases to active holo-synthases. Sfp is the PPTase necessary for installing PPant on the PCP of surfactin synthase

phosphopantetheinylation of IacP, i.e. SPI-1, a homologue of acyl carrier proteins. IacP from Salmonella enterica serovar Typhimurium is matured by addition of 4'-phosphopantetheine to the conserved serine 38 residue by enzyme AcpS, an enzyme normally required for the maturation of the canonical acyl carrier protein (ACP), which is involved in fatty acid biosynthesis. Interaction occurs between IacP and AcpS but not between IacP and the other PPTases, suggesting that AcpS is the PPTase responsible for the posttranslational modification occurring on IacP

dependent on, binding structure, overview. The edge strands beta4 and beta6 of the two beta-sheets provide the binding site for the CoA diphosphate and associated Mg2+ ion. The active site in Mtb-PptT is formed in the shallow cleft between the two domains, where CoA and Mg2+ are bound
additional information
-
CuSO4, CdCl2 and CrCl2 does not stimulate the reaction at any ceoncentration, trivalent metal cations such as FeCl3 or AlCl3 are ineffective
additional information
-
Ca2+, Fe2+, Co2+ and Zn2+ are ineffective, inhibitory or both, at intermediate and high concentrations
additional information
-
Mg2+ results in the highest activity among the divalent ions tested followed by Mn2+, while Ca2+ has no effect on the activity of the enzyme
