Xylene monooxygenase of Pseudomonas putida mt-2 catalyzes the methylgroup hydroxylation of toluene and xylenes. To investigate the potential of xylene monooxygenase to catalyze multistep oxidations of one methyl group, we tested recombinant Escherichia coli expressing the monooxygenase genes xylM and
