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