Maleate isomerase

In enzymology, a maleate isomerase is an enzyme that catalyzes the chemical reaction


 * maleate $$\rightleftharpoons$$ fumarate

Hence, this enzyme has one substrate, maleate, and one product, fumarate.

This enzyme belongs to the family of isomerases, specifically cis-trans isomerases. The systematic name of this enzyme class is maleate cis-trans-isomerase. This enzyme participates in butanoate metabolism and nicotinate and nicotinamide metabolism.
