We report here the in vivo expression of the synthetic transposase gene himar1(a) in Streptomyces coelicolor M145 and Streptomyces albus. Using the synthetic himar1(a) gene adapted for Streptomyces codon usage, we showed random insertion of the transposon into the streptomycetes genome. The insertion frequency for the Himar1-derived minitransposons is(More)
Streptomyces albus J1074 is a derivative of the S. albus G1 strain defective in SalG1 restriction–modification system. Genome sequencing of S. albus J1074 revealed that the size of its chromosome is 6.8 Mb with unusually short terminal arms of only 0.3 and 0.4 Mb. Here we present our attempts to evaluate the dispensability of subtelomeric regions of the S.(More)
The deletions of large genomic DNA fragments and consecutive gene knockouts are prerequisites for the generation of organisms with improved properties. One of the key issues in this context is the removal of antibiotic resistance markers from engineered organisms without leaving an active recombinase recognition site. Here, we report the establishment of an(More)
The rational modification of the actinomycetes genomes has a variety of applications in research, medicine, and biotechnology. The use of site-specific recombinases allows generation of multiple mutations, large DNA deletions, integrations, and inversions and may lead to significant progress in all of these fields. Despite their huge potential,(More)
The biosynthetically well-studied landomycin A cluster has been used to demonstrate the unbalancing of gene transcription as an efficient method for the generation of new compounds. Landomycin A structural genes were decoupled from the native regulators LanI and LanK and placed under the control of a single synthetic promoter and expressed in a heterologous(More)
