Valine-3-methyl-2-oxovalerate transaminase () is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme characterised from pea are L-valine and 3(S)-3-methyl-2-oxo-pentanoic acid. Its products are α-ketoisovaleric acid and L-isoleucine.
This enzyme is a transferase, specifically a transaminase, which transfer nitrogenous groups. The systematic name of this enzyme class is L-valine:(S)-3-methyl-2-oxopentanoate aminotransferase. Other names in common use include valine-isoleucine transaminase, valine-3-methyl-2-oxovalerate aminotransferase, alanine-valine transaminase, valine-2-keto-methylvalerate aminotransferase, and valine-isoleucine aminotransferase.
