WebMore than a hundred years ago, J. N. Collie coined the term “polyketide” to represent natural products derived from simple two-carbon CH 2-CO building blocks (Collie and Myers, 1893).This proposal was later proven experimentally by A. J. Birch who used isotopically labeled acetate in the study of 6-methylsalicylic acid (6MSA) biosynthesis in fungi and … Polyketide synthases (PKSs) are a family of multi-domain enzymes or enzyme complexes that produce polyketides, a large class of secondary metabolites, in bacteria, fungi, plants, and a few animal lineages. The biosyntheses of polyketides share striking similarities with fatty acid biosynthesis. The PKS … See more PKSs can be classified into three types: • Type I PKSs are large, complex protein structures with multiple modules which in turn consist of several domains that are usually covalently connected to each other and fulfill different … See more Each type I polyketide-synthase module consists of several domains with defined functions, separated by short spacer regions.
