In enzymology, an UDP-N-acetylmuramate dehydrogenase (EC 1.3.1.98) is an enzyme that catalyzes the chemical reaction

UDP-N-acetyl-alpha-D-muramate + NADP+ UDP-N-acetyl-3-O-(1-carboxyvinyl)-alpha-D-glucosamine + NADPH + H+

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, uridine-5'-diphospho-N-acetyl-2-amino-2-deoxy-3-O-lactylglucose:NADP-oxidoreductase. This enzyme participates in aminosugars metabolism. It employs one cofactor, FAD.

Structural studies

As of late 2007, 8 structures have been solved for this class of enzymes, with PDB accession codes 1HSK, 1MBB, 1MBT, 1UXY, 2GQT, 2GQU, 2MBR, and 2Q85.

In enzymology, an aspartate-semialdehyde dehydrogenase is an enzyme that is very important in the biosynthesis of amino acids in prokaryotes, fungi, and some higher plants. It forms an early branch point in the metabolic pathway forming lysine, methionine, leucine and isoleucine from aspartate. This pathway also produces diaminopimelate which plays an essential role in bacterial cell wall formation. There is particular interest in ASADH as disabling this enzyme proves fatal to the organism giving rise to the possibility of a new class of antibiotics, fungicides, and herbicides aimed at inhibiting it.
