Valine-pyruvate transaminase () is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme characterised from Escherichia coli are L-valine and pyruvic acid. Its products are α-ketoisovaleric acid and L-alanine.
This enzyme is a transferase, specifically a transaminase, which transfer nitrogenous groups. The systematic name of this enzyme class is L-valine:pyruvate aminotransferase. Other names in common use include transaminase C, valine-pyruvate aminotransferase, and alanine-oxoisovalerate aminotransferase. It participates in valine, leucine and isoleucine biosynthesis.
