High levels of copper are toxic and therefore bacteria must limit free intracellular levels to prevent cellular damage. In this study, we show that a number of pneumococcal genes are differentially regulated by copper, including an operon encoding a CopY regulator, a protein of unknown function (CupA) and a P1-type ATPase, CopA, which is conserved in all sequenced Streptococcus pneumoniae strains. Transcriptional analysis demonstrated that the cop operon is induced by copper in vitro, repressed ...[more]

CelR-mediated activation of the cellobiose-utilization gene cluster in Streptococcus pneumoniae

Project description:Comparison of the Streptococcus pneumoniae D39 celR mutant compared to D39 wild type in M17 medium+ 0.5 % (w/v) Cellobiose (CM17) The human pathogen Streptococcus pneumoniae harbors many genes encoding phosphotransferase systems (PTSs) and sugar ABC (ATP-binding cassette) transporters, including systems for the utilization of the ?-glucoside sugar cellobiose. In this study, we show that the transcriptional regulator CelR, which has previously been found to be important for pneumococcal virulence, activates the expression of the cellobiose-utilization gene cluster (cel locus) of S. pneumoniae. Expression directed by the two promoters present in the cel locus was increased in the presence of cellobiose as a sole carbon source in the medium, while expression decreased in the presence of glucose in the medium. Furthermore, we have predicted a 22-bp putative CelR regulatory site (5?-YTTTCCWTAWCAWTWAGGAAAA-3?) in the promoters of celA and celB and in silico analysis showed that it is highly conserved in other pathogenic streptococci as well. Promoter truncations of celA and celB, where the half or full CelR regulatory site was deleted, confirmed that the CelR binding site in PcelA and PcelB is functional. Transcriptome studies with the celR mutant and in silico prediction of the CelR regulatory site in the entire D39 genome sequence show that the cel locus is the only cluster of genes under the direct control of CelR. Therefore, CelR is a regulator dedicated to the cellobiose-dependent transcriptional activation of the cel locus. One condition design comparision of two strains including a dye swap

Transcriptome comparison of rokA mutant to wild-type in the Streptococcus pneumoniae D39.

Project description:The Gram-positive human pathogen Streptococcus pneumoniae possesses an unusually high number of gene clusters specific for carbohydrate utilization. This provides it with the ability to use a wide array of sugars, which may aid during infection and survival in different environmental conditions present in the host. In this study, the regulatory mechanism of transcription of a gene cluster, SPD0424-28, putatively encoding a cellobiose/lactose-specific PTS, is investigated. Upstream of SPD0424 a gene was identified encoding a ROK-family transcriptional regulator (RokA: SPD0423). DNA microarray and transcriptional reporter analyses with a rokA mutant revealed that RokA acts as a transcriptional repressor of the SPD0424-28 operon. In conclusion, we have characterized the role of RokA on gene expression of S. pneumoniae. One condition design comparision of two strains including a dye swap

Streptococcus pneumoniae bguR mutant vs wild-type D39

Project description:Transcriptome comparison of bguR mutant to wild-type in the Streptococcus pneumoniae D39 grown in GM17 The human pathogen Streptococcus pneumoniae has the ability to use the carbon- and energy source cellobiose due to the presence of a cellobiose-utilizing gene cluster (cel locus) in its genome. This system is regulated by the cellobiose-dependent transcriptional activator CelR, which has been previously shown to contribute to pneumococcal virulence. To get a broader understanding of the response of S. pneumoniae to cellobiose, we compared the pneumococcal transcriptome during growth on glucose as the main carbon source to that with cellobiose as the main carbon source. The expression of various carbon metabolic genes was altered, including a PTS operon (which we here denote as the bgu operon) that has high similarity with the cel locus. In contrast to the cel locus, the bgu operon is conserved in all sequenced strains of S. pneumoniae, indicating an important physiological function in the lifestyle of pneumococci. We next characterized the transcriptional regulation of the bgu operon in more detail. Its expression was increased in the presence of cellobiose, and decreased in the presence of glucose. A novel GntR-type transcriptional regulator (which we here denote as BguR) was shown to act as a transcriptional repressor of the bgu operon and its repressive effect was relieved in the presence of cellobiose. BguR-dependent repression was demonstrated to be mediated by a 20-bp DNA operator site (5M-bM-^@M-^Y-AAAAATGTCTAGACAAATTT-3M-bM-^@M-^Y) present in PbguA as verified by promoter truncation experiments. In conclusion, we have identified a new cellobiose-responsive PTS operon, together with its transcriptional regulator in S. pneumoniae.
