(Submitter supplied) The gene aml encoding alpha-amylase in Streptomyces lividans was cloned in the multicopy plasmid pIJ486, generating plasmid pAMI11. Plasmid pAMI11 and pIJ486 were propagated in S. lividans TK21 to obtain S. lividans TK21(pAMI11) and its isogenic strain S. lividans TK21(pIJ486). Transcriptional profiling of the bacterium that overproduces alpha-amylase mainly resulted in the upregulation of genes involved in the biogenesis and function of ribosomes, together with the upregulation of the genes involved in the redox processes, the ABC transporters, the central carbon, aminoacid and purine /pyrimidine metabolism. more...

(Submitter supplied) The gene dagA encoding agarase in Streptomyces coelicolor was cloned in the multicopy plasmid pIJ486 generating plasmid pAGAs5. Plasmid pAGAs5 and pIJ486 were propagated in S. lividans TK21 to obtain S. lividans TK21(pAGAs5) and its isogenic strain S. lividans TK21(pIJ486). Transcriptional profiling of the bacterium that overproduces agarase mainly resulted in the downregulation of the genes involved in the biogenesis and function of ribosomes, together with the downregulation of the genes involved in nitrogen, aminoacids, purine/pyrimidine and central carbon metabolism as well as ABC transporters, redox processes and fatty acids biosynthesis. more...

(Submitter supplied) The Streptomyces lividans lsp gene encodes a type II signal peptidase (Lsp) that cleaves the type II leader peptides of lipoproteins. Transcriptional profiling of the bacterium depleted of the lsp gene mainly resulted in deactivation of the sigma U regulon, as well as in downregulation of genes involved in the biogenesis and function of ribosomes and genes encoding some major secretory proteins as determined by hybridisation of commercially available S. more...

(Submitter supplied) Many biological processes are intrinsically dynamic, incurring profound changes at both molecular and physiological levels. Systems analyses of such processes incorporating large-scale transcriptome or proteome profiling can be quite revealing. Although consistency between mRNA and proteins is often implicitly assumed in such studies, instances of divergent trends are frequently observed indicating the existence of post-transcriptional regulation. more...

(Submitter supplied) Background The genomes of Streptomyces coelicolor and Streptomyces lividans bear a considerable degree of orthology. While S. coelicolor is the model streptomycete for studying antibiotic synthesis and differentiation, S. lividans is almost exclusively considered as the preferred host, among actinomycetes, for cloning and expression of exogenous DNA. We used whole genome microarrays as a comparative genomics tool for identifying the subtle yet crucial differences between these two chromosomes. more...

(Submitter supplied) Background. Transforming waste and non-food materials into bulk biofuels and chemicals represents a major stride in creating a sustainable bioindustry, optimizing the use of resources while reducing environmental footprints. Yet, despite these advancements, the production of high-value natural products often continues to rely on first-generation substrates, underscoring the intricate processes and specific requirements of their biosynthesis. more...
