Polyketide biosynthesis beyond the type I, II and III polyketide synthase paradigms.
Recent literature on polyketide biosynthesis suggests that polyketide synthases have much greater diversity in both mechanism and structure than the current type I, II and III paradigms. These examples serve as an inspiration for searching novel polyketide synthases to give new insights into polyketide biosynthesis and to provide new opportunities for combinatorial biosynthesis.
متن کاملBiosynthesis of aliphatic polyketides by type III polyketide synthase and methyltransferase in Bacillus subtilis.
Type III polyketide synthases (PKSs) synthesize a variety of aromatic polyketides in plants, fungi, and bacteria. The bacterial genome projects predicted that probable type III PKS genes are distributed in a wide variety of gram-positive and -negative bacteria. The gram-positive model microorganism Bacillus subtilis contained the bcsA-ypbQ operon, which appeared to encode a type III PKS and a m...
متن کاملPKSIIIexplorer: TSVM approach for predicting Type III polyketide synthase proteins
UNLABELLED PKSIIIexplorer, a web server based on 'transductive Support Vector Machine' allows fast and reliable prediction of Type III polyketide synthase proteins. It provides a simple unique platform to identify the probability of a particular sequence, being a type III polyketide synthases or not with moderately high accuracy. We hope that our method could serve as a useful program for the t...
متن کاملThe chalcone synthase superfamily of type III polyketide synthases.
This review covers the functionally diverse type III polyketide synthase (PKS) superfamily of plant and bacterial biosynthetic enzymes. from the discovery of chalcone synthase (CHS) in the 1970s through the end of 2001. A broader perspective is achieved by a comparison of these CHS-like enzymes to mechanistically and evolutionarily related families of enzymes, including the type I and type II P...
متن کاملType I polyketide synthase requiring a discrete acyltransferase for polyketide biosynthesis.
Type I polyketide synthases (PKSs) are multifunctional enzymes that are organized into modules, each of which minimally contains a beta-ketoacyl synthase, an acyltransferase (AT), and an acyl carrier protein. Here we report that the leinamycin (LNM) biosynthetic gene cluster from Streptomyces atroolivaceus S-140 consists of two PKS genes, lnmI and lnmJ, that encode six PKS modules, none of whic...
