Hence, this enzyme has one substrate, vinylacetyl-CoA, and one product, crotonyl-CoA.
This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases transposing C=C bonds. The systematic name of this enzyme class is vinylacetyl-CoA Delta3-Delta2-isomerase. Other names in common use include vinylacetyl coenzyme A Delta-isomerase, vinylacetyl coenzyme A isomerase, and Delta3-cis-Delta2-trans-enoyl-CoA isomerase. This enzyme participates in butanoate metabolism.
Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 1U8V.
