IUBMB Comments

The enzyme, characterized from the bacteria Hydrogenobaculum sp. and Syntrophomonas wolfei subsp. wolfei and from the archaea Metallosphaera sedula and Ignisphaera aggregans, can use both NADH and NADPH with similar efficiency [cf. EC 1.1.1.86, ketol-acid reductoisomerase (NADP+) and EC 1.1.1.382, ketol-acid reductoisomerase (NAD+)].

The expected taxonomic range for this enzyme is: Archaea, Bacteria, Eukaryota

Synonyms
ilvC, Shewana3_0355, more
