Genetic studies of Streptomyces cattleya and Streptomyces olivaceus
… VCll is able to virulently infect 11 of the 20 Streptomyces strains tested. Examination of VCll infection of Streptomyces cattleya, Streptomyces olivaceus and Streptomyces lividans TC10 indicated the absence of restriction-modification systems which affect VCll infectivity of these Streptomyces …

Investigation of Streptomyces promoters
… promoters. Initially the suitability of the Streptomyces antibioticus me1C operon for use as a reporter system in Streptomyces was investigated. It was established that late-expressed promoters could be identified and that it was possible to use the me1C2 gene alone for this purpose. However, …

Glucan metabolism in mycobacterium and streptomyces
… distant relatives of mycobacteria. In this study Streptomyces venezuelae was used to show for the first time that the GlgE pathway is responsible for glucan synthesis in vivo, as was predicted by the annotations in the genome. A ΔglgE mutant was devoid of α-glucan and instead accumulated α-maltose …

Inhibition of Hsp90 in Streptomyces coelicolor
… the effect of Hsp90 inhibition on the bacteria Streptomyces coelicolor. These changes were studied by growing S. coelicolor in the presence of Hsp90 inhibitors, extracting the growth media, and subjecting the extractions to HPLC and MS analysis. It has been found that reproducibility is …

Investigating the genome complexity of Streptomyces clavuligerus
Streptomyces clavuligerus is the producer of clavulanic acid; a β-lactamase inhibitor that isused in combination with the antibiotic amoxicillin to treat many bacterial infections. The unique genome of S. clavuligerus includes a chromosome, and four linear plasmids pSCL1, pSCL2, pSCL3 and the …

MarR Family Transcriptional Regulators from Streptomyces coelicolor
… methyltransferase regulator) and PecS in Streptomyces coelicolor were studied to investigate their potential role in this bacterium. In Streptomyces coelicolor, the gene (SCO3133), which encodes TamR, is oriented divergently from the tam gene, which encodes trans-aconitate …

The streptomyces cytoskeletal protein (Scy) is a key component of the tip organising centre for polarized growth in streptomyces coelicolor
The Gram-positive bacterium Streptomyces coelicolor, is one of the main genetic model organisms in the phylum of the Actinobacteria. Streptomyces bacteria are soil dwelling filamentous bacteria with a complex life cycle consisting of multigenomic hyphae that then form unicellular spores. Bacterial …

Taxonomic problems associated with named strains of Streptomyces cinnamonensis
Streptomyces cinnamonensis ATCC 15413 is the source of monensin which is an antibiotic used as a coccidiostat and feed-additive. My thesis is a report of a comparative taxonomic study of seven strains of Streptomyces cinnamonensis including ATCC 15413, using methods devised by the International …
