Enzyme Information

2.2.1.6
Acetolactate synthase.
based on mapping to UniProt P17597
2 pyruvate = 2-acetolactate + CO(2).
-!- The reaction shown is in the pathway of biosynthesis of valine. -!- The enzyme can also transfer the acetaldehyde from pyruvate to 2-oxobutanoate, forming 2-ethyl-2-hydroxy-3-oxobutanoate, also known as 2-aceto-2-hydroxybutanoate, a reaction in the biosynthesis of isoleucine. -!- Formerly EC 4.1.3.18.
