Definition of ilvC

Curated proteins or TIGRFams with EC 1.1.1.86
Curated proteins or TIGRFams with EC 1.1.1.382
Curated proteins or TIGRFams with EC 1.1.1.383
Curated sequence CH_123630: mitochondrial ketol-acid reductoisomerase
Comment: The three EC numbers correspond to different preferences for NAD(P)H as the cofactor; the transformations to the carbon skeleton are the same. CH_123630 is added because it is annotated as this but with no EC number.
