structure-based substrate specificity, macrolide binding analysis, overview. Although erythromycin, clarithromycin, oleandomycin, and azithromycin differ in the size of the lactone ring and varying substitutions, the 14- and 15-membered ring substrates bind to the two MPH enzymes in a similar location, adopt similar conformations, and interact with the enzymes in a similar manner. MPH(2')-I cannot modify 16-membered macrolides, in contrast to MPH(2')-II |

Unlike MPH(2')-I, MPH(2')-II can efficiently modify 16-membered macrolides. The 16-membered rings are more ovoid in shape compared with the rounded shape of the 14- and 15-membered macrolides. The interactions between MPH(2')-II and the 16-membered macrolides, spiramycin and josamycin, are similar to those of the 14- and 15-membered macrolides, involving many of the same amino acid side chains |
