title: Proteomic analysis of polyketide and nonribosomal peptide biosynthesis.
abstract: Polyketides and non-ribosomal peptides are in a class of natural products important both as drug sources and as dangerous toxins and virulence factors. While studies over the last two decades have provided substantial characterization of the modular synthases that produce these compounds at the genetic level, their understanding at the protein level is much less understood. New proteomic platforms called an orthogonal active site identification system (OASIS) and proteomic interrogation of secondary metabolism (PrISM) have been developed to identify and quantify natural product synthase enzymes. Reviewed here, these tools offer the means to discover and analyze modular synthetic pathways that are limited by genetic techniques, opening the tools of contemporary proteomics to natural product sciences.
