Different strains of E. coli have the ability to utilize certain aromatic acids as the sole source of carbon. Shown here, E. coli K-12 can grow on both 3-phenylpropanoate and 3-(3-hydroxyphenyl)propanoate [Burlingame83]. For the complete degradation pathway, please see the superpathway 3-phenylpropanoate and 3-(3-hydroxyphenyl)propanoate degradation.

Note that MhpB and MhpC are the only enzymes in this pathway that have been biochemically characterized.
