UDP-N-acetylmuramate dehydrogenase

In enzymology, an UDP-N-acetylmuramate dehydrogenase () is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are UDP-N-acetyl-alpha-D-muramate and NADP⁺, whereas its 3 products are UDP-N-acetyl-3-O-(1-carboxyvinyl)-alpha-D-glucosamine, NADPH, and H⁺.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD⁺ or NADP⁺ as acceptor. The systematic name of this enzyme class is UDP-N-acetyl-alpha-D-muramate:NADP⁺ oxidoreductase. Other names in common use include MurB reductase, UDP-N-acetylenolpyruvoylglucosamine reductase, UDP-N-acetylglucosamine-enoylpyruvate reductase, UDP-GlcNAc-enoylpyruvate reductase, uridine diphosphoacetylpyruvoylglucosamine reductase, uridine diphospho-N-acetylglucosamine-enolpyruvate reductase, . This enzyme participates in aminosugars metabolism. It employs one cofactor, FAD.
