(Submitter supplied) CcpA is a global regulator of transcription in Gram-positive bacteria that controls gene expression in response to carbohydrate availability. Using the fructan hydrolase (fruA) gene of S. mutans as a model, we demonstrate that CcpA does indeed play a major role in carbohydrate catabolite repression. Using DNA microarrays, the expression of at least 170 genes differed in CcpA-deficient cells compared to the parental strains when cells are grown in the presence of glucose, but only 90 genes showed altered expression when cells were cultivated in the poorly-repressing substrate galactose. more...

(Submitter supplied) The goal of this study were to compare the transcriptoms of CcpA and CovR in group A Streptococcus. Isogenic mutant strains were created in which CcpA and CovR were inactivated alone and in combination. The transcriptomes of the four strains (wild-type, CcpA mutant, CovR mutant, and ccpA-covR double mutant) were then compared.

(Submitter supplied) In Bacillus cereus the catabolite control protein CcpA was shown to be involved in optimizing the efficiency of glucose catabolism by activating genes encoding glycolytic enzymes including a non-phosphorylating glyceraldehyde-3-phosphate dehydrogenase that mediates conversion of D-glyceraldehyde 3-phosphate to 3-phospho-D-glycerate in one single step, and by repressing genes encoding the citric acid cycle and gluconeogenic enzymes. more...

(Submitter supplied) We explored the regulatory mechanism of Leloir pathway genes in Streptococcus pneumoniae D39. Here, we demonstrate that the expression of galKT is galactose dependent. By microarray analysis and quantitative RT-PCR, we further show the role of the transcriptional regulator GalR, present upstream of galKT, as a transcriptional activator of galKT in the presence of galactose. Moreover, we predict a 19-bp regulatory site (5'-GATAGTTTAGTAAAATTTT-3' ) for the transcriptional regulator GalR in the promoter region of galK, which is also highly conserved in other streptococci. more...

(Submitter supplied) Comparison of the Streptococcus pneumoniae D39 spxB- mutant vs D39. For DNA microarray analysis, D39 wild-type and two independently obtained D39spxB- mutants were grown as four, two and two biological replicates, respectively, in Glc-M17 under semi-aerobic conditions and harvested at an OD595 of approximately 0.25 (mid-exponential). The RNA of both D39spxB- strains was compared to D39 and the combined data was analyzed. more...
