In enzymology, a maleylpyruvate isomerase (EC 5.2.1.4) is an enzyme that catalyzes the chemical reaction

3-maleylpyruvate [math]\displaystyle{ \rightleftharpoons }[/math] 3-fumarylpyruvate

Hence, this enzyme has one substrate, 3-maleylpyruvate, and one product, 3-fumarylpyruvate.

This enzyme belongs to the family of isomerases, specifically cis-trans isomerases. The systematic name of this enzyme class is 3-maleylpyruvate cis-trans-isomerase. This enzyme participates in tyrosine metabolism.

Structural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 2NSF and 2NSG.
