enzyme displays hysteresis, observed as a lag in progress curves, and is sensitive to product inhibition during the lag. The inhibition results in a systematic decrease in steady-state velocity and makes the lag appear to have a second-order dependence on enzyme concentration.The lag is in fact due to a substrate and cofactor-induced isomerization of the enzyme. The cofactor binds to the enzyme:substrate complex with negative cooperativity, suggesting that the isomerization may be related to the formation of an asymmetric enzyme complex

malfunction

Haloferax volcanii cells deleted of HVO_1531 present a modified S-layer
malfunction
mutant dimeric species of UGDH have reduced activity in vitro and in supporting hyaluronan production by cultured cells. The purified enzymes reveal a significant decrease in the enzymatic activity of the obligate dimer and hexamer mutants. Both T325A and T325D mutants were significantly less efficient in promoting downstream hyaluronan production by HEK293 cells
malfunction
UGDH protein level in rat osteoarthritis cartilage are much lower than the corresponding controls and negatively correlated to the degree of osteoarthritis
malfunction
UGDH specific siRNAs markedly inhibits UGDH mRNA and protein expression, and leads to an obvious suppression of proteoglycans synthesis in human articular chondrocytes. UGDH protein level in human osteoarthritis cartilage are much lower than the corresponding controls and negatively correlated to the degree of osteoarthritis. Interleukin-1beta inhibits UGDH gene expression through modulating UGDH transregulators and the downstream signaling cascades, including the SAP/JNK and p38 MAPK pathways which might be involved in the proteoglycans loss of osteoarthritis cartilage and contribute to the osteoarthritis pathogenesis

enzyme displays a NAD+-dependent SN2 mechanism. The first oxidation involves the nucleophilic addition of the essential Cys residue. The acceptor of C6-OH of UDP-glucose is an ordered H2O molecule. The second NADH is released after hydrolysis of the thioester intermediate

physiological function

UDP-glucose dehydrogenase is responsible for the NAD-dependent twofold oxidation of UDP-glucose to UDP-glucuronic acid, one of the key components for gellan biosynthesis
physiological function
-
UGDH oxidizes UDP-glucose to UDP-glucuronate, an essential precursor for production of hyaluronan, proteoglycans, and xenobiotic glucuronides. High levels of hyaluronan turnover in prostate cancer are correlated with aggressive progression. UGDH expression is high in the normal prostate even though hyaluronan accumulation is virtually undetectable. The enzyme's common role in the prostate may be to provide precursors for glucuronosyltransferase enzymes, which inactivate and solubilize androgens by glucuronidation. Androgen dependence of UGDH, glucuronosyltransferase, and hyaluronan synthase expression, overview
physiological function
enzyme displays hysteresis, observed as a lag in progress curves, and is sensitive to product inhibition during the lag. The inhibition results in a systematic decrease in steady-state velocity and makes the lag appear to have a second-order dependence on enzyme concentration.The lag is in fact due to a substrate and cofactor-induced isomerization of the enzyme. The cofactor binds to the enzyme:substrate complex with negative cooperativity, suggesting that the isomerization may be related to the formation of an asymmetric enzyme complex. The hysteresis may be the consequence of a functional adaptation, by slowing the response of the enzyme to sudden increases in the flux of substrate, the other biochemical pathways that use this important metabolite will have a competitive edge
physiological function
precise allelic exchange mutagenesis of isoform hasB in strain 5448, a representative of the globally disseminated M1T1 serotype, does not abolish hyaluronic acid capsule synthesis due to presence of paralog HasB2. Mutagenesis of HasB2 alone slightly decreases capsule abundance. A HasB HasB2 double mutant becomes completely acapsular

enzyme AglM can be functionally replaced by another UDP-glucose dehydrogenase, VNG1048G, in vivo
physiological function
enzyme VNG1048G can functionally replace another UDP-glucose dehydrogenase AglM in vivo. In Halobacterium salinarum, where glycoproteins are modified by an N-linked glycan of similar composition, gene VNG1048G is not only found within a cluster of N-glycosylation-related genes reminiscent of the genomic region surrounding its Haloferax volcanii counterpart AglM but can also functionally replace gene aglM in a Haloferax volcanii strain lacking the gene

physiological function
UGDH is essential in the proteoglycan synthesis in articular chondrocytes, overview. UDP-glucuronic acid is a key precursor for the synthesis of the glycosaminoglycan chain in proteoglycans
physiological function
enzyme is involved in capsular polysaccharide biosynthesis
physiological function
epirubicin accumulation increases and apoptosis decreases during UGDH knockdown. Hyaluronan-coated matrix increases and a positive modulation of autophagy is detected. Higher levels of UGDH are correlated with worse prognosis in triple-negative breast cancer patients that receive chemotherapy. High expression of UGDH is found in tumoral tissue from HER2--patients. UGDH knockdown contributes to epirubicin resistance
physiological function
in breast cancer cells, depletion of the hyaluronic acid precursor UDP-glucuronic acid is sufficient to inhibit several mesenchymal-like properties including cellular invasion and colony formation in vitro, as well as tumor growth and metastasis in vivo. Depletion of UDP-glucuronic acid alters the expression of PPAR-gamma target genes and increases PPAR-gamma DNA binding activity
physiological function
knocking out UGDH in highly metastatic 6DT-1 breast cancer cells impairs migration ability without affecting in vitro proliferation. UGDH-KO results in significantly decreased metastatic capacity in vivo when the cells are orthotopically injected in syngeneic mice

the ectopic overexpression of UGDH4 in Arabidopsis thaliana significantly increases the contents of hemicellulose and soluble sugar
physiological function
-
transgenic Arabidopsis lines overexpressing GH_D12G1806 have longer root lengths and higher gene expression level than the wild-type plants of Columbia-0. At flowering stage, the number of trichomes on the sepals of transgenic lines increases significantly, to about 155% of that of the control plants. Compared with the Col-0, most of the trichomes on the main stem of transgenic lines show bifurcated phenotypes
physiological function
UDP-glucose dehydrogenase Ugd2 is involved in building capsular polysaccharides K20 and K21. The K20 and K21 capsular polysaccharides include GlcpA produced by Ugd2 and D-galactose with an (R)-configured 4,6-pyruvic acid acetal added by Prt2. The first sugar in the tetrasaccharide K units is 2-acetamido-4-amino-2,4,6-trideoxy-D-glucose (D-QuipNAc4N) that carries a 4-N-[(S)-3-hydroxybutanoyl] group in some K units and a 4-N-acetyl group in the others

precise allelic exchange mutagenesis of isoform hasB in strain 5448, a representative of the globally disseminated M1T1 serotype, does not abolish hyaluronic acid capsule synthesis due to presence of paralog HasB2. Mutagenesis of HasB2 alone slightly decreases capsule abundance. A HasB HasB2 double mutant becomes completely acapsular
