| Accepted name: |
β-methylindole-3-pyruvate reductase |
| Reaction: |
(2S,3R)-2-hydroxy-3-(indol-3-yl)butanoate + NAD+ = (R)-3-(indol-3-yl)-2-oxobutanoate + NADH + H+ |
| Glossary: |
(R)-3-(indol-3-yl)-2-oxobutanoate = (R)-β-methylindole-3-pyruvate
(2S,3R)-2-hydroxy-3-(indol-3-yl)butanoate = indolmycenate |
| Other name(s): |
ind2 (gene name) |
| Systematic name: |
(2S,3R)-2-hydroxy-3-(indol-3-yl)butanoate:NAD+ oxidoreductase |
| Comments: |
The enzyme, characterized from the bacterium Streptomyces griseus, participates in the biosynthesis of indolmycin, an antibacterial drug that inhibits the bacterial tryptophan—tRNA ligase (EC 6.1.1.2). |
