The final step in the biosynthesis of methymycin, neomethymycin, and picromycin is an hydroxylation, shown to be carried out by the cytochrome P-450 monooxygenase, PicK. Direct comparison of the relative Kcat/K(m) values for the two substrates, YC-17 and narbomycin, showed a threefold rate preference of picK for narbomycin.
