Complementation of daptomycin dptA and dptD deletion mutations in trans and production of hybrid lipopeptide antibiotics. The core of each module consists of a KS, acyltransferase (AT), and ACP domain. Antibiotics (1991) 44:357-365 demonstrated that the avermectin polyketide synthase was somewhat flexible in choice of starter units. Since nonribosomal peptide assembly lines use carrier proteins similar to those use in polyketide synthases, convergence of the two systems evolved to form hybrids, resulting in polypeptides with nitrogen in the skeletal structure and complex function groups similar to those found in amino acids.[21]. You are using a browser version with limited support for CSS. 4, 195202 (1997). Examples of polyketides include: Macrolides; Pikromycin, the first isolated macrolide; the antibiotics erythromycin A; clarithromycin, and azithromycin; the immunosuppressant tacrolimus; Radicicol and Pochonin family (HSP90 inhibitor); Polyene antibiotics; Amphotericin; Tetracyclines and the tetracycline family of antibiotics. 105, 715738 (2005). Microbiol. [8] In addition, further advancements in biotechnology have allowed for the use of metagenomics and genome mining to find new polyketides using similar enzymes to known polyketides. Google Scholar. Open Access [19] There are various subclasses of polyketides including: aromatics, macrolactones/macrolides, decalin ring containing, polyether, and polyenes. J Antibiot 69 , 494 .

Bookshelf 2017 Jan 10;12(1):e0169851. In type II polyketide synthases (PKSs), which typically biosynthesize several antibiotic and antitumor compounds, the substrate is a growing polyketide chain, shuttled between individual PKS enzymes, while covalently tethered to an acyl carrier protein (ACP): this requires the ACP interacting with a series of different enzymes in succession.

Our strategy was to replace the loading module of DEBS, which accepts propionyl coenzyme A (CoA) and acetyl-CoA in vivo (), with the loading module from the avermectin-producing polyketide synthase of Streptomyces avermitilis, which has an unusually broad specificity for branched carboxylic acids as starter units in vivo (). SIM News 55, 186196 (2005).
