UDP-glucose 6-dehydrogenase

UDP-glucose 6-dehydrogenase

In enzymology, an UDP-glucose 6-dehydrogenase (EC number|1.1.1.22) is an enzyme that catalyzes the chemical reaction

:UDP-glucose + 2 NAD+ + H2O ightleftharpoons UDP-glucuronate + 2 NADH + 2 H+

The 3 substrates of this enzyme are UDP-glucose, NAD+, and H2O, whereas its 3 products are UDP-glucuronate, NADH, and H+.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is UDP-glucose:NAD+ 6-oxidoreductase. Other names in common use include UDP-glucose dehydrogenase, uridine diphosphoglucose dehydrogenase, UDPG dehydrogenase, UDPG:NAD oxidoreductase, UDP-alpha-D-glucose:NAD oxidoreductase, UDP-glucose:NAD+ oxidoreductase, uridine diphosphate glucose dehydrogenase, UDP-D-glucose dehydrogenase, and uridine diphosphate D-glucose dehydrogenase. This enzyme participates in 4 metabolic pathways: pentose and glucuronate interconversions, ascorbate and aldarate metabolism, starch and sucrose metabolism, and nucleotide sugars metabolism.

tructural studies

As of late 2007, 5 structures have been solved for this class of enzymes, with PDB accession codes PDB link|1DLI, PDB link|1DLJ, PDB link|2O3J, PDB link|2Q3E, and PDB link|2QG4.
