In enzymology, an UDP-N-acetylglucosamine 6-dehydrogenase (EC 1.1.1.136) is an enzyme that catalyzes the chemical reaction

UDP-N-acetyl-D-glucosamine + 2 NAD+ + H2O UDP-N-acetyl-2-amino-2-deoxy-D-glucuronate + 2 NADH + 2 H+

The 3 substrates of this enzyme are UDP-N-acetyl-D-glucosamine, NAD+, and H2O, whereas its 3 products are UDP-N-acetyl-2-amino-2-deoxy-D-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-N-acetyl-D-glucosamine:NAD+ 6-oxidoreductase. Other names in common use include uridine diphosphoacetylglucosamine dehydrogenase, UDP-acetylglucosamine dehydrogenase, UDP-2-acetamido-2-deoxy-D-glucose:NAD oxidoreductase, and UDP-GlcNAc dehydrogenase. This enzyme participates in aminosugars metabolism.

Tunicamycin is a mixture of homologous nucleoside antibiotics that inhibits the UDP-HexNAc: polyprenol-P HexNAc-1-P family of enzymes. In eukaryotes, this includes the enzyme GlcNAc phosphotransferase (GPT), which catalyzes the transfer of N-acetylglucosamine-1-phosphate from UDP-N-acetylglucosamine to dolichol phosphate in the first step of glycoprotein synthesis. Tunicamycin blocks N-linked glycosylation (N-glycans) and treatment of cultured human cells with tunicamycin causes cell cycle arrest in G1 phase. It is used as an experimental tool in biology, e.g. to induce unfolded protein response. Tunicamycin is produced by several bacteria, including Streptomyces clavuligerus and Streptomyces lysosuperificus.
