ENZYME entry: EC 1.17.5.1

PURL: https://purl.expasy.org/enzyme/EC/1.17.5.1
Accepted Name
phenylacetyl-CoA dehydrogenase
Alternative Name(s)
phenylacetyl-CoA:acceptor oxidoreductase
Reaction catalysed
phenylacetyl-CoA + 2 a ubiquinone + H2O = phenylglyoxylyl-CoA + 2 a ubiquinol
Comment(s)
  • The enzyme is specific for phenylacetyl-CoA as substrate.
  • Phenylacetate, acetyl-CoA, benzoyl-CoA, propanoyl-CoA, crotonyl-CoA, succinyl-CoA and 3-hydroxybenzoyl-CoA cannot act as substrates.
  • The oxygen atom introduced into the product, phenylglyoxylyl-CoA, is derived from water and not molecular oxygen.
  • Duroquinone, menaquinone and 2,6-dichlorophenolindophenol (DCPIP) can act as acceptor, but the likely physiological acceptor is ubiquinone.
  • A second enzyme, EC 3.1.2.25 converts the phenylglyoxylyl-CoA formed into phenylglyoxylate.
