Name | KARI C-terminal domain |
| Function | Ketol-acid reductoisomerase (KARI; EC 1.1.1.86), also known as acetohydroxy acid isomeroreductase (AHIR or AHAIR), catalyzes the conversion of acetohydroxy acids into dihydroxy valerates in the second step of the biosynthetic pathway for the essential branched-chain amino acids valine, leucine, and isoleucine. KARIs are composed of two types of domains, an N- terminal Rossmann fold domain and one or two C-terminal knotted domains. |
| Scope(s) |
