Maltose epimerase

In enzymology, a maltose epimerase is an enzyme that catalyzes the chemical reaction


 * alpha-maltose $$\rightleftharpoons$$ beta-maltose

Hence, this enzyme has one substrate, alpha-maltose, and one product, beta-maltose.

This enzyme belongs to the family of isomerases, specifically those racemases and epimerases acting on carbohydrates and derivatives. The systematic name of this enzyme class is maltose 1-epimerase.
