Abstract

Coelibactin is a putative non-ribosomally synthesized peptide with predicted zincophore activity and which has been implicated in antibiotic regulation in Streptomyces coelicolor A3(2). The coelibactin biosynthetic pathway contains a stereo- and regio-specific monooxygenation step catalyzed by a cyt...
