Biosynthesis of Salinosporamides from α,β-Unsaturated Fatty Acids: Implications for Extending Polyketide Synthase Diversity
摘要:
A new series of coenzyme A-tethered polyketide synthase extender units were discovered in relation to the biosynthesis of the salinosporamide family of anticancer agents from the marine bacterium Salinispora tropica. In vivo and in vitro experiments revealed that the crotonyl-CoA reductase/carboxylase SalG has broad substrate tolerance toward 2-alkenyl-CoAs that give rise to the salinosporamide C-2 substitution pattern.

natural product biosynthetic gene clusters. These predictions are supported by the demonstration that a phylogenetically distant homolog of TcsD also regioselectively oxidizes α,β-unsaturated substrates. This work exemplifies a powerful approach to understand unique enzymatic reactions and will facilitate future enzyme discovery, inform enzyme engineering, and aid natural productcharacterization efforts
