Mechanisms for incorporation of glycerol-derived precursors into polyketide metabolites

Abstract

Several polyketide secondary metabolites are shown by feeding experiments to incorporate glycerol-derived 3-carbon starter units, 2-carbon extender units, or 3-carbon branches into their hydrocarbon chains. In recent years, genetic studies have begun to elucidate the mechanisms by which this occurs. In this article we review the incorporation of glycerol-derived precursors into polyketides and propose new mechanisms for the incorporation processes. © Society for Industrial Microbiology 2005.
