A key intermediate in aerobic catabolism of phenylacetate in bacteria
Phenylacetyl-coenzyme A (CoA) is a key intermediate in aerobic catabolism of phenylacetate in bacteria such as Pseudomonas, when cultured in minimal media using phenylacetate as the sole carbon source.1 It is a precursor in the synthesis of the antibiotic penicillin G found in industrial strains of P. chrysogenum. Phenylacetyl-CoA also acts as an effector molecule of the TetR family transcriptional repressor PaaR in T. thermophilus and the GntR family transcriptional regulator PaaX in E. coli and Pseudomonas, binding to each protein to induce derepression of various genes.2
