Accepted name: ethylbenzene hydroxylase
Reaction: ethylbenzene + H2O + acceptor = (S)-1-phenylethanol + reduced acceptor

Other name(s): ethylbenzene dehydrogenase; ethylbenzene:(acceptor) oxidoreductase
Systematic name: ethylbenzene:acceptor oxidoreductase
Comments: Involved in the anaerobic catabolism of ethylbenzene by denitrifying bacteria. Ethylbenzene is the preferred substrate; the enzyme from some strains oxidizes propylbenzene, 1-ethyl-4-fluorobenzene, 3-methylpent-2-ene and ethylidenecyclohexane. Toluene is not oxidized. p-Benzoquinone or ferrocenium can act as electron acceptor. Contains molybdopterin, [4Fe-4S] clusters and heme b.
