Proline racemase

In enzymology, a proline racemase is an enzyme that catalyzes the chemical reaction


 * L-proline $$\rightleftharpoons$$ D-proline

Hence, this enzyme has one substrate, L-proline, and one product, D-proline.

This enzyme belongs to the family of isomerases, specifically those racemases and epimerases acting on amino acids and derivatives. The systematic name of this enzyme class is proline racemase. This enzyme participates in arginine and proline metabolism.
