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. The order of modules and domains of a complete polyketide-synthase is as follows (in the order N-terminus See more Only about 1% of all known molecules are natural products, yet it has been recognized that almost two thirds of all drugs currently in … See more • Polyketide+synthases at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more The growing chain is handed over from one thiol group to the next by trans-acylations and is released at the end by hydrolysis or … See more Polyketide synthases are an important source of naturally occurring small molecules used for chemotherapy.
