evolution
the enzyme belongs to the the UGDH family of proteins
evolution
the N- and C-terminal domains of UgdG share structural features with ancient mitochondrial ribonucleases named MAR. MARs are present in lower eukaryotic microorganisms, have a Rossmannoid-fold and belong to the isochorismatase superfamily
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
metabolism
in the Haloferax volcanii archaeal glycosylation pathway, Agl, responsible for the assembly and attachment of an Asn-linked pentasaccharide, enzyme AglM acts as a UDP-glucose dehydrogenase, converting UDP-glucose into UDP-glucuronic acid
metabolism
the enzyme participates in sucrose/polysaccharide metabolism and cell wall biosynthesis

dysregulated expression of UGDH can promote the development of androgen independent tumor cell growth by increasing available levels of intracellular androgen. UGDH activity is the rate limiting factor in solubilization of excess androgen from prostate tumor cells, overview

enzyme Ugd from Escherichia coli K-12 can functionally replace enzyme Ugd from Escherichia coli serotype K30 in biosynthesis of K30 capsular polysaccharide
