<p> This 3-hydroxyacyl-CoA dehydrogenase is involved in the degradation of phenylacetic acid, presumably in steps following the opening of the phenyl ring [<cite idref="PUB00010200"/>]. The sequences included in this entry are all found in possible operons with other related genes such as paaA, paaB, paaD, paaE, paaF and paaN [<cite idref="PUB00015494"/>]. Some genomes contain these other genes without an apparent paaC in the same operon - possibly in these cases a different dehydrogenase involved in fatty acid degradation may fill in the needed activity. </p> 3-hydroxyacyl-CoA dehydrogenase PaaC
