-
protein glutamine + alkylamine = protein N5-alkylglutamine + NH3
the first step in both types of modifications is the acylation of the active site cysteine (Cys277) of TG2 by a protein-bound glutamine residue, resulting in the liberation of ammonia and the formation of a thioester intermediate between TG2 and the glutamine bearing protein substrate. In TG2 catalyzed transamidation, the thioester intermediate is attacked by a nucleophilic primary amine, either a small molecule amine such as putrescine or the epsilon-amino group of protein-bound lysine residues. This results in the formation of relatively stable isopeptide bonds
-
protein glutamine + alkylamine = protein N5-alkylglutamine + NH3
the catalytic reaction follows a modified ping-pong mechanism in which a glutamine-containing protein or peptide, the acyl-donor substrate, reacts with the catalytic cysteine residue to form a thioester bond. The resulting covalent acyl-enzyme intermediate then reacts with a second substrate, the acyl-acceptor, to yield the isopeptide-containing product and free enzyme in a transamidation reaction.

TGase induces rapid aggregation of amyloid beta-protein within 0.5â30 min, which is not observed with chemical cross-linkers. Both amyloid beta-protein40 and amyloid beta-protein42 are good substrates for TGase but show different aggregation patterns. Guinea pig and human TGase induced similar amyloid beta-protein aggregation patterns, and oligomerization is observed with amyloid beta-protein40 concentrations as low as 50 nM. The formed amyloid beta-protein40 species ranges from 5 to 6 nm spheres to curvilinear structures of the same width, but up to 100 nm in length. TGase-induced amyloid beta-protein40 assemblies are resistant to a 1 h incubation with either neprilysin or insulin degrading enzyme, whereas the monomer is rapidly degraded by both proteases

synthesis and kinetic characterisation of water-soluble fluorogenic acyl donors for transglutaminase 2, overview. Development of a fluorimetric TGase 2 activity assay with release of 7-hydroxycoumarin (HC) by TGase 2-catalysed hydrolysis or aminolysis of Z-Phe-gamma-Abu-HC resulting in a measureable increase in fluorescence. No activity with Z-Phe-gamma-Abu-7-amido-4-methylcoumarin and Z-Glu(AMC)-Gly-OH. Because the assay of TGase 2 requires the presence of an antioxidant to prevent oxidation of the active-site cysteine residue, both DTT and tris(2-carboxyethyl)phosphine (TCEP) are employed for investigations into the spontaneous reactivity of the compounds at a concentration of 0.5 mM. C-terminal extension with glycine results in kobs values that are increased by a factor of approximately four

wild-type TG2 can catalyze synthesis of CBZ-protected dipeptides. Its donor substrate specificity is narrow, aromatic ester derivatives of Gly and D-Ala serve as donor substrates. A hydrophobic cavity formed by Trp332 and Phe334 dictates substrate specificity. TG2 enzymes exhibit broad specificity towards the acyl-acceptor substrate. Guinea pig liver transglutaminase (gTG2) catalyzes the cross-linking of peptides and proteins via the formation of gamma-glutamyl-epsilon-lysyl isopeptide bonds. gTG2-catalyzed peptide bond formation between various amino acid-derived donor and acceptor substrates is analyzed. gTG2 forms Gly-Xaa and D-Ala-Gly dipeptide products, confirming that the enzyme's natural transamidation activity can be co-opted for peptide synthesis, LC-MS analysis. An aromatic ester of Gly is the most efficient acyl-donor substrate tested, aromatic esters of D-Ala and L-Ala show 50fold lower reactivity or no reactivity, respectively. The native acyl-acceptor substrate is generally a lysine-containing protein or peptide, many nonnatural primary amines, such as glycinamide, and anilines, such as N,N-dimethyl-1,4-phenylenediamine, can also react. TG2 displays narrow specificity for its acyl-donor substrates. The side chain of a protein or peptide-bound L-Gln residue is the native substrate while the side chain of the similar amino acid L-Asn is not reactive. In addition to amides, gamma-glutamyl aromatic ester derivatives of L-Glu, such as Ncarbobenzyloxy-L-glutamyl(gamma-p-nitrophenyl ester)glycine, have also been shown to be acyl-donor substrates of TG2 and are used to measure the enzyme's activity. N-Carbobenzyloxyglycyl-coumarin-7-yl ester (CBZ-Gly-7HC), is also a donor substrate of TG2. Construction of acyl-enzyme intermediates, structure analysis, and structural basis, overview

functions of TG2: wound healing, macrophage phagocytosis, TGF-beta activation, protein kinase activity, association with calreticulin, and association with G-protein coupled receptor GPR56. The majority of these functions are independent of the enzymatic transamidation activity of the protein. Transglutaminase 2 is involved in the pathogenesis of a number of diseases, such as celiac sprue, neurodegenerative disorders, diabetes, liver cirrhosis and fibrosis, renal scarring, and certain types of cancer. It is the enzymatic function of TG2 that is thought to contribute to the pathology or etiology of most of the aforementioned diseases

posttranslational dimerization and multimerization of Camelidae anti-human TNF single domain antibodies in vitro catalyzed by microbial transglutaminases. Ribonuclease S-tag-peptide acts as a peptidyl substrate in covalent protein cross-linking reactions catalyzed by MTG. C-terminally fusion of the S-tag sequence to the anti-hTNF-variable heavy chain-domain results in fusion proteins that are efficiently dimerized and multimerized by MTG whereas anti-hTNF-variable heavy chain domain is not susceptible to protein crosslinking

microbial transglutaminase (MTG) is a practical tool to enzymatically form isopeptide bonds between peptide or protein substrates. Engineered, highly reactive substrates of microbial transglutaminase enable protein labeling within various secondary structure elements. MTG can react readily with glutamines in alpha-helical, beta-sheet, and unstructured loop elements and does not favor one type of secondary structure. Building of a GB1 library where each variant contains a single glutamine at positions covering all secondary structure elements, detailed overview. The most reactive and selective variants display an over 100fold increase in incorporation compared to another developed aminated benzo[a]imidazo[2,1,5-cd]indolizine-type fluorophore, relative to native GB1

site-specific conjugation to native and engineered lysines in human immunoglobulins by microbial transglutaminase, overview. ESI-MS analysis of antibodies incubated with an acyl donor substrate and enzyme MTG, performed by incubation with ZQG-biotin and MTG at 37°C overnight followed by digestion with IdeS to generate Fab'2 and Fc fragments. A positive-control peptide with two known lysine acyl acceptor sites (GGSTKHKIPGGS) is genetically fused to the C-terminus of mAb1 HC or LC (HC-KTag or LC-KTag, respectively) and analyzed for transamidation. The addition of the KTag to the HC C-terminus blocks removal of Lys447, thereby allowing MTG to utilize Lys447 as an acyl acceptor site. Effect of single C-terminal amino acids on transamidation of HC Lys447, and analysis of transamidation of single lysine substitutions in gamma, iota, kappa, and lambda constant regions, overview. Optimal transamidation of an LC C-terminal lysine requires a spacer between Cys214 and the lysine. Analysis of transamidation of select single lysine substitutions, conducted by incubating samples with ZQG-biotin and MTG at 37°C overnight. Mutational analysis of binding sites

site-specific transglutaminase-mediated conjugation of interferon alpha-2b at glutamine or lysine residues. Reactivity of IFN alpha-2b to microbial transglutaminase (TGase) allows site-specific conjugation of this protein drug. Production of two monoderivatized isomers of IFN with high yields, mass spectrometry analysis of the two conjugates indicating that they are exclusively modified at the level of Gln101 if the protein is reacted in the presence of an amino-containing ligand (i.e. dansylcadaverine) or at the level of Lys164 if a glutamine-containing molecule is used (i.e. carbobenzoxy-L-glutaminyl-glycine, ZQG). The enzyme is absolutely specific, among the 10 Lys and 12 Gln residues of the protein, only Gln101 and Lys164 are located in highly flexible protein regions

the enzymatic transamidation reaction between a gamma-glutamyl donor (Z-Gln-Gly) and hydroxylamine releasing ammonia is coupled to the glutamate dehydrogenase (GDH)-catalyzed reductive amination of 2-oxoglutarate. The activity of GDH is dependent on NADH as a cofactor, whose disappearance can be monitored at 340 nm. NADH concentration was calculated based on a calibration curve, which in turn is used to calculate activity of mTG
