CRYSTAL STRUCTURE OF NARBOMYCIN-BOUND CYTOCHROME P450 PIKC (CYP107L1)

Overview

The pikromycin (Pik)/methymycin biosynthetic pathway of Streptomyces, venezuelae represents a valuable system for dissecting the fundamental, mechanisms of modular polyketide biosynthesis, aminodeoxysugar assembly, glycosyltransfer, and hydroxylation leading to the production of a series, of macrolide antibiotics, including the natural ketolides narbomycin and, pikromycin. In this study, we describe four x-ray crystal structures and, allied functional studies for PikC, the remarkable P450 monooxygenase, responsible for production of a number of related macrolide products from, the Pik pathway. The results provide important new insights into the, structural basis for the C10/C12 and C12/C14 hydroxylation patterns for, the 12-(YC-17) and 14-membered ring (narbomycin) macrolides, ...
