Project description:ArlRS is a two-component regulatory system in Staphylococcus aureus. Here we use RNA-sequencing to compare gene expression in a wild-type USA300 strain and an isogenic arlRS mutant.
Project description:MgrA is a global regulator of gene expression in Staphylococcus aureus. Here we use RNA-sequencing to compare gene expression in a wild-type USA300 strain and an isogenic mgrA mutant.
Project description:To study the roles of NWMN_0641, we used microarray to compare the transcriptome of the NWMN_0641 deletion strain with that of the wild-type Staphylococcus aureus Newman strain. Transcriptome of the NWMN_0641 deletion mutant strain and the wild-type Newman strain
Project description:Vancomycin-intermediate Staphylococcus aureus (VISA) evolve in a strain-specific manner and acquire mutations that lead to alterations in cell wall metabolism that reduce susceptibility to vancomycin. We had earlier isolated several VISA mutant strains of the clinical hVISA strain MM66. This study is aimed at analyzing the metabolome of these mutants in comparison to the parent strain.
Project description:Accurate annotation of regulatory RNAs is a complex task but nevertheless essential as sRNA molecular and functional studies ensue from it. Several formerly considered small RNAs (sRNA) are now known to be parts of UTR transcripts. In light of experimental data, we review hundreds of Staphylococcus aureus putative regulatory RNAs. We pinpoint those that are likely acting in trans and are not expressed from the opposite strand of a coding gene. We conclude that HG003, a NCTC8325 derivative strain, has about 50 bona fide sRNAs, indicating that these RNAs are less numerous than commonly stated.
