Polyketide synthases and nonribosomal peptide synthetases: the emerging view from bacterial genomics.
نویسندگان
چکیده
A total of 223 complete bacterial genomes are analyzed, with 281 citations, for the presence of genes encoding modular polyketide synthases (PKS) and nonribosomal peptide synthetases (NRPS). We report on the distribution of these systems in different bacterial taxa and, whenever known, the metabolites they synthesize. We also highlight, in the different bacterial lineages, the PKS and NRPS genes and, whenever known, the corresponding products.

Non-linear enzymatic logic in natural product modular mega-synthases and -synthetases.
Modular polyketide synthases and nonribosomal peptide synthetases are giant multienzymes that catalyze the assembly of a wide variety of bioactive natural products including several important clinical drugs. In simple mechanical terms, these systems function as molecular assembly lines, where each domain in the multienzyme performs its task once during the assembly process. However, several pol...
متن کاملTailoring enzymes acting on carrier protein-tethered substrates in natural product biosynthesis.
Carrier proteins (CPs) are integral components of fatty acid synthases, polyketide synthases, and nonribosomal peptide synthetases and play critical roles in the biosynthesis of fatty acids, polyketides, and nonribosomal peptides. An emerging role CPs play in natural product biosynthesis involves tailoring enzymes that act on CP-tethered substrates. These enzymes provide a new opportunity to en...
متن کاملEstablishing a new methodology for genome mining and biosynthesis of polyketides and peptides through yeast molecular genetics.
Fungal genome sequencing has revealed many genes coding for biosynthetic enzymes, including polyketide synthases and nonribosomal peptide synthetases. However, characterizing these enzymes and identifying the compounds they synthesize remains a challenge, whether the genes are expressed in their original hosts or in more tractable heterologous hosts, such as yeast. Here, we developed a streamli...
متن کاملDraft Genome Sequence of Streptomyces sp. TP-A0356, a Producer of Yatakemycin
Here, we report the draft genome sequence of Streptomyces sp. TP-A0356, a producer of a potent antitumor antibiotic, yatakemycin, to evaluate potential for secondary metabolite production. The genome sequence data suggest the presence of at least nine gene clusters for polyketide synthases and nonribosomal peptide synthetases in this strain.
متن کاملDiscovery Strategies of Bioactive Compounds Synthesized by Nonribosomal Peptide Synthetases and Type-I Polyketide Synthases Derived from Marine Microbiomes
Considering that 70% of our planet's surface is covered by oceans, it is likely that undiscovered biodiversity is still enormous. A large portion of marine biodiversity consists of microbiomes. They are very attractive targets of bioprospecting because they are able to produce a vast repertoire of secondary metabolites in order to adapt in diverse environments. In many cases secondary metabolit...
