(A) Schematic diagram of the phenylacetic acid (PAA) catabolic pathway (adapted from reference 45 with permission). (B) Genetic organization of the paa gene cluster in C. glutamicum strain AS 1.542, C. glutamicum strain R, C. efficiens YS-314, and E. coli K-12 MG1655. Homologous genes are presented in the same color, and the proposed enzyme names are listed at the bottom. The amino acid sequence similarities (expressed as percentages) of paa genes in Corynebacterium strains with those in E. coli K-12 are shown. N/A, not applicable; the paaT and paaR genes do not exist in E. coli K-12.
