THE CRYSTAL STRUCTURE OF MACROLIDE GLYCOSYLTRANSFERASES: A BLUEPRINT FOR ANTIBIOTIC ENGINEERING
OverviewOverview
Glycosylation of macrolide antibiotics confers host cell immunity from, endogenous and exogenous agents. The Streptomyces antibioticus, glycosyltransferases, OleI and OleD, glycosylate and inactivate, oleandomycin and diverse macrolides including erythromycin, respectively., The structure of these enzyme-ligand complexes, in tandem with kinetic, analysis of site-directed variants, provide insight into the interaction, of macrolides with their synthetic apparatus. Erythromycin binds to OleD, and the 23S RNA of its target ribosome in the same conformation and, although the antibiotic contains a large number of polar groups, its, interaction with these macromolecules is primarily through hydrophobic, contacts. Erythromycin and oleandomycin, when bound to OleD and OleI, respectively, adopt different conformations, reflecting a subtle effect on, sugar positioning by virtue of a single change in the macrolide backbone., The data reported here provide structural insight into the mechanism of, resistance to both endogenous and exogenous antibiotics, and will provide, a platform for the future redesign of these catalysts for antibiotic, remodelling.
