Enables enzyme regulator activity. Contributes to acetolactate synthase activity. Involved in branched-chain amino acid biosynthetic process. Located in mitochondrial nucleoid. Part of acetolactate synthase complex.
SGD Description
Regulatory subunit of acetolactate synthase; acetolactate synthase catalyzes the first step of branched-chain amino acid biosynthesis; enhances activity of the Ilv2p catalytic subunit, localizes to mitochondria
