MC001.To introduce the tmc cluster into S. coelicolor TMC003, the apramycin-resistant gene of pMMBL101 was replaced by a spectinomycin-resistant gene (named pMMBL102) employing a Fast Quick BAC modification kit (GeneBridges). The Red/ET plasmid was introduced into pMMBL101-containing E. coli EPI300, after which BAC modification was performed in accordance with the manufacturer’s guide utilizing PCR to amplify the spectinomycin-resistant gene inside the aprR-homologous area. Transformants were selected on spectinomycincontaining LB medium and confirmed by PCR. Right after pMMBL102 was transformed into E. coli S17-1, it was introduced into S. coelicolor TMC003 by conjugation.Fast genome sequencing of Streptomyces sp.

CK4412-TMC001 was ready from 3-days culture having a WizardGenome DNA Purification Kit (Promega). The genomic DNA was fragmented by dsDNA fragmentase to make proper size for library construction. Resulting DNA fragments was processed to Illumine Nextera DNA sample preparation kit (Illumina, Inc., USA) following manufacturer’s instruction. Final library was quantified by Bioanalyzer 2100 (Agilent, USA) and typical library size was 300 bp. The genomic library was sequenced by Illumina MiSeq (Illumina, Inc.Klotho Protein Source , USA). Generated paired-end sequencing reads (23,891,700 process reads) had been assembled working with CLC genomics workbench 6.0 (CLC bio, Denmark) and resulted in 253 contigs. The contigs and PCR-based long reads had been combined by means of manual curation by utilizing CodonCode Aligner three.7.1 (CodonCode Corp., Dedham, MA, USA). The final plasmid sequence was corrected by remapping with raw reads to check errors and dubious regions.PMID:23927631 The coding sequences (CDS) have been predicted by Glimmer 3.02 [31]. tRNA had been identified by tRNA-ScanSE [32], and rRNA had been searched using HMMER with EzTaxon-e rRNA profiles [33, 34]. The predicted CDSs have been when compared with catalytic families (catFam) and NCBI COG by rpsBLAST and NCBI reference sequences (RefSeq) and SEED databases by BLASTP for functional annotation [358].References 1.
