Project description:We identified genome-wide binding regions of NdgR in Streptomyces coelicolor using chromatin immunoprecipitation sequencing (ChIP-seq). We constructed 6×myc-tagged NdgR strain using homologous recombination with myc-tagging vector. Analysis of the sequencing data aligned to Streptomyces coelicolor genome database (NC_003888).

Project description:Actinomycete genomes contain a plethora of orphan gene clusters encoding unknown secondary metabolites, and representing a huge unexploited pool of chemical diversity. The explosive increase in genome sequencing and the massive advance of bioinformatic tools have revolutionized the rationale for natural product discovery from actinomycetes. In this context, we applied a genome mining approach to discover a group of unique catecholate-hydroxamate siderophores termed as qinichelins from Streptomyces sp. MBT76. Quantitative proteomics statistically correlated a gene cluster of interest (qch) to its unknown chemotype (qinichelin), after which structural elucidation of isolated qinichelin was assisted by bioinformatics analysis and verified by MS2 and NMR experiments. Strikingly, intertwined functional crosstalk among four separately located gene clusters was implicated in the biosynthesis of qinichelins.

Project description:Investigation of whole genome gene expression level changes in Streptomyces sp. SirexAA-E (ActE) when grown on different carbon sources. The results of this study demonstrate that ActE upregulates a small number of genes specific for the utilization of the avaliable carbon source. Cellulolytic Streptomyces sp. SirexAA-E (ActE), isolated from the pinewood-boring wasp Sirex noctilio, has a genome enriched for biomass utilization. The secreted proteomes obtained from growth on pure polysaccharides catalyzed hydrolysis of cellulose, mannan, and xylan with specific activities comparable to Spezyme CP, a commercial cellulase preparation. During reaction of an ActE secretome with cellulose, reducing sugar release was markedly stimulated in the presence of O2. ActE also expresses and secretes an expanded repertoire of enzymes during growth on natural and pre-treated biomass. These results indicate a new microbial contribution to biomass utilization that is widely distributed in natural environments by insects

Project description:Brevibacillus sp. SPR20 produced potentially antibacterial substances against MRSA. The synthe-sis of these substances is controlled by their biosynthetic gene clusters. Several mutagenesis methods are used to overcome the restriction of gene regulations when genetic information is ab-sent. Atmospheric and room temperature plasma (ARTP) is a powerful technique to make random mutagenesis for microbial strain improvement. This study utilized an argon-based ARTP to conduct the mutations on SPR20. The positive mutants of 40% occurred. The M27 mutant exhib-ited an increase in anti-MRSA activity when compared to the wild-type, by which the MIC values were 250500 and 500 g/mL, respectively. M27 had genetic stability because it exhibited con-stant activity throughout 15 generations. This mutant had similar morphology and antibiotic susceptibility to the wild-type. Comparative proteomic analysis identified some specific proteins that were upregulated in M27. These proteins were involved in the metabolism of amino acids, cell structure and movement, and catalytic enzymes. These might result in the enhancement of the anti-MRSA activity of the ARTP-treated SPR20 mutant. This study supports the ARTP technology to increase the production of valuable antibacterial agents.
