Copies of chromosome Streptomyces coelicolor A3(2) fragment (gene coding polyketide syntase of III type) were obtained to use polymerase cycle reaction. Amplified DNA was cloned in shuttle vector pWHM4 on sites for HindIII and EcoRI. The restriction analysis of plasmid DNAs of transformants has demonstrated that molecular size of cloned DNA fragment was 1134 bp.

Production of specialized metabolites are restricted to the metabolic capabilities of the organisms. Genome-scale models (GEM)s are useful to study the whole metabolism and to find metabolic engineering targets to increase the yield of a target compound. In this work we use a modified model of Streptomyces coelicolor M145 to simulate the production of lagmysin A (LP4) and the novel lagmysin B (LP2) lasso peptide, in the heterologous host Streptomyces coelicolor M1152.

The calcium-dependent antibiotics (CDAs) are a group of seven closely related membrane-active cyclic lipopeptide antibiotics (cLPAs) first isolated in the early 1980s from the fermentation broth of . Their target was unknown, and the mechanism of action is uncertain. Herein, we report new routes for the synthesis of CDA4b and its analogues, explore the structure-activity relationships at its lipid tail and at positions 3, 9, and 11, and determine the CDAs' lipid target.

, a common foodborne pathogen, has a close association with agriculture and food. With the rapid emergence and widespread dissemination of antimicrobial resistance, efforts have been directed toward developing and studying new antimicrobial compounds to inhibit the growth of and other foodborne pathogens, thereby preventing contamination and ensuring food safety. Herein, we reported eight new aromatic polyketides, naphpyrones A-H (-), from the heterologous expression strain A3(2)/ ΔH3.

RNA-seq and its 5'-enrichment methods for prokaryotes have enabled the precise identification of transcription start sites (TSSs), improving gene expression analysis. Computational methods are applied to these data to identify TSSs and classify them based on proximal annotated genes. While some TSSs cannot be classified at all (orphan TSSs), other TSSs are found on the reverse strand of known genes (antisense TSSs) but are not associated with the direct transcription of any known gene.
