In vivo and in vitro reconstitution of unique key steps in cystobactamid antibiotic biosynthesis

Abstract

The biosynthetic pathway leading to the production of cystobactamids, a group of myxobacteria-derived topoisomerase inhibitors with potent anti-Gram-negative activity, remains unclear. Here, the authors report in vivo and in vitro evidence for unique steps in cystobactamid biosynthesis.
