Function
function
Catalyzes the conversion of 2 pyruvate molecules into acetolactate in the first common step of the biosynthetic pathway of the branched-amino acids such as leucine, isoleucine, and valine.
Catalytic activity
- H+ + 2 pyruvate = (2S)-2-acetolactate + CO2
Pathway
Amino-acid biosynthesis; L-isoleucine biosynthesis; L-isoleucine from 2-oxobutanoate: step 1/4.
Amino-acid biosynthesis; L-valine biosynthesis; L-valine from pyruvate: step 1/4.
