Steps Towards Deciphering the Post-Polyketide Synthase Tailoring Steps in the Phoslactomycin Biosynthesis Pathway

TL;DRAbstract

Phoslactomycins (PLMs) are a group of natural products belonging to a polyketides class. These polyketides are synthesized by sequential reaction catalyzed by a collection of enzymes activities called polyketide synthases. A polyketide is a large class of diverse compounds that are characterized by more than two carbonyl groups connected by single intervening carbon atoms. In other words, a polyketide is a polymer whose monomer is a ketide. The PLMs are also known as phosphazomycins or phospholines. These compounds were isolated based on antifungal and antitumor activities. This array of promising biological activities has stimulated research into the field of PLMs for treatment of various diseases such as aspergillosis. A significant success has been reported in understanding and manipulating PLM biosynthesis. However, its post-polyketide biosynthetic mechanism remains to be elucidated. In this study, we established steps needed to pave the way for the elucidation of the post-polyketi
