ENZYME entry: EC 1.17.5.1

Accepted Name
Phenylacetyl-CoA dehydrogenase.
Alternative Name(s)
Phenylacetyl-CoA:acceptor oxidoreductase.
Reaction catalysed
Phenylacetyl-CoA + H(2)O + 2 quinone <=> phenylglyoxylyl-CoA + 2 quinol
Cofactor(s)
Iron-sulfur; Mo-molybdopterin.
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.
