Summary
PaaABCDE is a multi-subunit oxygenase that hydroxylates phenylacetyl-CoA. [More information is available at EcoGene: EG14299]. PaaA, PaaB, PaaC, and PaaD are predicted to be subunits of a phenylacetate-CoA oxygenase involved in phenylacetate catabolism . [More information is available at EcoCyc: G6710].
