AC PRU01198; DC Domain; TR PROSITE; PS51851; KARI_C; 1; level=0 XX Names: 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. XX CC -!- SIMILARITY: Belongs to the ketol-acid reductoisomerase family.
