Alpha-methylacyl-CoA racemase

In enzymology, an alpha-methylacyl-CoA racemase is an enzyme that catalyzes the chemical reaction


 * (2S)-2-methylacyl-CoA $$\rightleftharpoons$$ (2R)-2-methylacyl-CoA

Hence, this enzyme has one substrate, (2S)-2-methylacyl-CoA, and one product, (2R)-2-methylacyl-CoA.

This enzyme belongs to the family of isomerases, specifically those racemases and epimerases acting on other compounds. The systematic name of this enzyme class is 2-methylacyl-CoA 2-epimerase.
