Organization of genes for protocatechuate catabolism in P. putida and Acinetobacter. The structures of inducing metabolites are shown. Arrows indicate the transcriptional activator genes pcaR and pcaU. They encode proteins that are similar in sequence and bind to similar operators, but the proteins respond to different inducers.
