Genetic analysis of polyketide synthase and peptide synthase genes of cyanobacteria as a mining tool for new pharmaceutical compounds
Cyanobacteria are considered a promising source for new pharmaceutical lead compounds and a large number of chemically diverse and bioactive metabolites have been obtained from cyanobacteria. Despite of several worldwide studies on prevalence of NRPSs and PKSs among the cyanobacteria, none of them included Iranian cyanobacteria of Kermanshah province. Therefore, the aim of this study was t...
متن کاملType I polyketide synthases that require discrete acyltransferases.
The diverse structures of polyketide natural products are reflected by the equally diverse polyketide biosynthetic enzymes, namely polyketide synthases (PKSs). Three major classes of PKSs are known-noniterative type I PKSs, iterative type II PKSs and acyl carrier protein-independent type III PKSs, each of which consists of additional variants. One such variant is the noniterative type I PKS in ...
متن کاملEngineering Microbes for Plant Polyketide Biosynthesis
Polyketides are an important group of secondary metabolites, many of which have important industrial applications in the food and pharmaceutical industries. Polyketides are synthesized from one of three classes of enzymes differentiated by their biochemical features and product structure: type I, type II or type III polyketide synthases (PKSs). Plant type III PKS enzymes, which will be the main...
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...
متن کاملNovel polyketide synthase from Nectria haematococca.
We identified a polyketide synthase (PKS) gene, pksN, from a strain of Nectria haematococca by complementing a mutant unable to synthesize a red perithecial pigment. pksN encodes a 2,106-amino-acid polypeptide with conserved motifs characteristic of type I PKS enzymatic domains: beta-ketoacyl synthase, acyltransferase, duplicated acyl carrier proteins, and thioesterase. The pksN product groups ...
