RESUMO
In primary metabolism, fatty acid synthases (FASs) biosynthesize fatty acids via sequential Claisen-like condensations of malonyl-CoA followed by reductive processing. Likewise, polyketide synthases (PKSs) share biosynthetic logic with FAS which includes utilizing the same precursors and cofactors. However, PKS biosynthesize structurally diverse, complex secondary metabolites, many of which are pharmaceutically relevant. This digest covers examples of interconnected biosynthesis between primary and secondary metabolism in fatty acid and polyketide metabolism. Taken together, further understanding the biosynthetic linkage between polyketide biosynthesis and fatty acid biosynthesis may lead to improved discovery and production of novel drug leads from polyketide metabolites.
