ordered sequential Bi Bi mechanism, overview. Pyrimidine bases may approach the base binding site, but they cannot form the tight interactions observed in the HpUGPase/UDP-Glc complex. Thymine binding would be hindered by its extra methyl group, and cytosine could not make specific hydrogen bonds

COMMENTARY
LITERATURE
evolution
-
a feature that discriminates UGPs of different species is the quaternary organization. While UGPs in protists are monomers, di- and tetrameric forms exist in bacteria, and the enzyme from yeast and human are octameric UGPs
evolution
-
the plant UGPases belongs to the so called UGPase-A family
malfunction
-
lack of sulfoquinovosyldiacylglycerol in the Arabidopsis ugp3 knockout mutant. The mutant does not show significant differences in glycosides and saccharides between wild type and ugp3 mutants

-

metabolism
D3HTY9
the enzyme catalyzes the last and reversible step of the de novo UDP-Glc biosynthetic pathway
metabolism
-
the enzyme is important in sulfoquinovosyldiacylglycerol, SQDG, biosynthesis in chloroplasts together with UDP-sulfoquinovose synthase, SQD1 EC 3.13.1.1, and SQDG synthase, SQD2, mechanism for SQDG biosynthesis, overview. Sulfoquinovosyldiacylglycerol is the only sulfur-containing anionic glycerolipid, a relatively minor relatively minor, and is the least prevalent component of photosynthetic membrane lipids. The function of SQDG under phosphate-limited growth conditions is highly correlated with the regulation of other plant glycerolipid biosyntheses. UGP3 is not involved in the biosynthesis of secondary metabolites and cellulose, but rather is likely to be specifically involved in SQDG synthesis
metabolism
-
UDPG-pyrophosphorylase is the key enzyme involved in pullulan biosynthesis and pullulan production by Aureobasidium pullulans
metabolism
-
UGP2 is unable to replace UGP1 in the UGP1 knockout lines, even though it bears similar metabolic functions to UGP. The majority of proteins that are responsive to FB1 treatment are located in the chloroplast and have functions associated with photosynthesis

physiological function
C7GP37
the enzyme is essential for survival
physiological function
Q9M4X0
OsUgp2 plays an important role in pollen starch accumulation, complicated transcriptional regulation of OsUgp2. The spatio-temporal expression of the gene is mostly codetermined by the types, numbers and positions of cisregulatory elements within the promoter region
physiological function
-
the enzyme is a critical factor that regulates FB1-induced programmed cell death, an active form of cell suicide that is tightly regulated at the genetic level, only being activated when required, mechanism, overview
physiological function
Q8GQP8
the enzyme plays an important role in Streptococcus zooepidemicus cell envelope hyaluronic acid biosynthesis and it is also recognized as a virulence determinant in several bacterial species
physiological function
-
UDP-Glc pyrophosphorylase is an essential enzyme responsible for production of UDP-Glc, which is used in hundreds of glycosylation reactions involving addition of Glc to a variety of compounds
physiological function
D3HTY9
UDP-glucose is the onyl precuror for UDP-galactose synthesis, which is one of the sugar nucleotides essentially required for the parasite's survival and infectivity. UDP-glucose is also the glucosyl donor for the unfolded glycoprotein glucosyltransferase involved in glycoprotein quality control in the endoplasmic reticulum and is the presumed donor for the synthesis of base J, i.e. beta-D-glucosyl-hydroxymethyluracil, a rare deoxynucleotide found in telomereproximal DNA in the bloodstream form of the parasite
physiological function
-
UGP3 is a plastid UDP-glucose pyrophosphorylase that supplies UDP-glucose to UDP-sulfoquinovose synthase, SQD1, in plastids
physiological function
O25363
UGPase is crucial in carbohydrate metabolism since UDP-Glc is used for the biosynthesis of glycogen and many other carbohydrate derivatives such as glycolipids, glycoproteins and proteoglycans

structure comparison of human and yeast enzyme, overview. Depolymerization of hUGPase, like in mutant N491P/L492E, results in monomers and higher enzymatic activity
additional information
-
structure modeling, overview. The quaternary structure of the enzyme is affected by addition of either single or both substrates in either direction of the reaction, resulting in a shift from UGPase dimers toward monomers, the active form of the enzyme. The substrate-induced changes in quaternary structure of the enzyme may have a regulatory role to assure maximal activity

structure modeling, overview. The quaternary structure of the enzyme is affected by addition of either single or both substrates in either direction of the reaction, resulting in a shift from UGPase dimers toward monomers, the active form of the enzyme. The substrate-induced changes in quaternary structure of the enzyme may have a regulatory role to assure maximal activity. The ratio of monomers to dimers is about 5:1 in absence of substrate

in complex with both Mg2+ and UDP-glucose. Residues involved in anchoring the ligand to the active site include the polypeptide chain backbone atoms of Ala20, Gly21, Gly117, Gly180, and Ala214, and the side chains of Glu36, Gln112, Asp143, Glu201, and Lys202. Two magnesium ions are coordinated to the UDP-glucose. An alpha- and a beta-phosphoryl oxygen, three waters, and the side chain of Asp142 ligate the first Mg2+ ion, whereas the second ion is coordinated by an alpha-phosphoryl oxygen and five waters; in presence of both magnesium and UDP-glucose. Residues anchoring the ligand to the acitve site include polypepetide backbone atoms of A20, G21, G117, G180 and A214 and side chain residues of E36, Q112, D143, E201, and K202. Two magnesium ions coordinate to UDP-glucose
Q6M6R3
protein is a tetramer with 222 point group symmetry. Each subunit is dominated by an eight-stranded mixed beta-sheet with two additional layers of beta-sheets and ten alpha-helices. Q109 and D137 anchor the uracil ring and the ribose of UDP-glucose to the protein.The beta-phosphoryl group of the product lies close to the epsilon-nitrogen of K202, the carboxylate group of E201 can bridge the 2- and 3-hydroxyl groups of the glucosyl moiety; to 1.9 A resolution. Modeling of UDP-glucose into the active site. The side chains of Gln109 and Asp137, respectively, serve to anchor the uracil ring and the ribose of UDP-glucose to the protein. The beta-phosphoryl group of the product is predicted to lie within hydrogen bonding distance to the eosilon-nitrogen of Lys202 whereas the carboxylate group of Glu201 is predicted to bridge the 2'- and 3'-hydroxyl groups of the glucosyl moiety

mutant enzyme DC005 shows the same thermostability as wild-type ST0452 protein, whereas mutant enzyme DC011 denatures and becomes insoluble form by 5-min treatment at 80 C. The C-terminal domain of the ST0452 protein, with its LbetaH structure, appears to be essential for the formation of its trimeric form and, in turn, the high stability of the entire ST0452 protein

enzyme gene disruption mutant reduces the survival of Aeromonas hydrophila in serum to less than 1%, decreases the ability of strains to adhere and reduces by 1.5 or 2 log units the virulence of Aeromonas serotype O34 strains in a septicaemia model. The mutant shows two types of lipopolysaccharide structures. The first one corresponds to a rough strain having the complete core, but lacking the terminal galactose residue from the LPS-core and 4-amino-4-deoxyarabinose residues from phosphate groups in lipid A. The second one corresponds to a deeply truncated structure with the LPS-core restricted to one 3-deoxy-D-manno-oct-2-ulosonic acid and three L-glycero-D-manno-heptose residues

the UTP-glucose-1-phosphate uridylyltransferase activity of mutant enzyme DC005 is reduced by 10%, as compared to that of the wild-type ST0452 protein, while the activity of DC011 is increased by 18%, indicating that the enzymatic activity in the N-terminal region is not greatly affected by truncation of the C-terminal 5 or 11 residues. The mutant enzyme DC011 (deletion of the C-terminal 11 residues of the ST0452 protein) shows little thermal stability at 80C. The C-terminal domain of the ST0452 protein, with its LbetaH structure, appears to be essential for the formation of its trimeric form and, in turn, the high stability of the entire ST0452 protein. The deletion mutant enzymes DC021, DC031, DC041, DC071 and DC121, are produced in an insoluble form or aggregated immediately after purification. Mutant enzymes DC051 and DC171 can be expressed in a soluble form. Mutant enzyme DC051 becomes completely insoluble after 5 min treatment at 60C, while mutant enzyme DC171 is insoluble after 5 min treatment at 70 C
