In enzymology, an UDP-N-acetylglucosamine 4-epimerase is an enzyme that catalyzes the chemical reaction
UDP-N-acetyl-D-glucosamine
\rightleftharpoons
Hence, this enzyme has one substrate, UDP-N-acetyl-D-glucosamine, and one product, UDP-N-acetyl-D-galactosamine.
This enzyme belongs to the family of isomerases, specifically those racemases and epimerases acting on carbohydrates and derivatives. The systematic name of this enzyme class is UDP-N-acetyl-D-glucosamine 4-epimerase. Other names in common use include UDP acetylglucosamine epimerase, uridine diphosphoacetylglucosamine epimerase, uridine diphosphate N-acetylglucosamine-4-epimerase, and uridine 5'-diphospho-N-acetylglucosamine-4-epimerase. This enzyme participates in aminosugars metabolism.
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and .
