Data class Domain;
Predictors PROSITE; PS51851; KARI_C
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) Bacteria
Archaea
Eukaryota
Example(s) A7GMU0 (ILVC_BACCN);
