| EC Number | 2.2.1.6 |
| CAS Registry Number | 9027-45-6 |
| Comments | This enzyme requires thiamine diphosphate. 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. |
| Cofactor | thiamine diphosphate |
| History | |
| Reactions | 2 pyruvate = 2-acetolactate + CO(2). |
