Assessment of CcpA-mediated catabolite control of metabolism and enterotoxin production in Bacillus cereus ATCC 14579

(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...

Analysis of the CcpA regulon in Staphylococcus aureus

(Submitter supplied) Background The catabolite control protein A (CcpA) is a member of the LacI/GalR family of transcriptional regulators controlling carbon-metabolism pathways in low-GC Gram positive bacteria. It functions as a catabolite repressor or activator, allowing the bacteria to utilize the preferred carbon source over secondary carbon sources. This study is the first CcpA-dependent transcriptome and proteome analysis in S. more...

The Role of CcpA in Gene Regulation in Streptococcus mutans

(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...

CcpA, a Pleiotropic Key Regulator in Butanol-producing Clostridium acetobutylicum ATCC 824

(Submitter supplied) Clostridium acetobutylicum is a typical bacterium of major importance to industrial butanol production. In order to dissect the regulatory network pertaining to the industrial application of this bacterium, catabolite control protein A (CcpA) was investigated for its global function by DNA microarray.It showed that CcpA of C. acetobutylicum controls hundreds of genes, not only carbon metabolism, but also solvent production and sporulation in the life cycle.The results here demonstrated that CcpA is an important pleiotropic regulator related to some specific physiological and biochemical process in butanol-producing C. more...

High- and low-affinity cre boxes for CcpA binding in Bacillus subtilis revealed by genome-wide analysis

(Submitter supplied) In Bacillus subtilis and its relatives carbon catabolite control, a mechanism enabling to reach maximal efficiency of carbon and energy sources metabolism, is achieved by the global regulator CcpA (carbon catabolite protein A). CcpA in a complex with HPr-Ser-P (seryl-phosphorylated form of histidine-containing protein, HPr) binds to operator sites called catabolite responsive elements, cre. Depending on the cre box position relative to the promoter, the CcpA/HPr-Ser-P complex can either act as a positive or a negative regulator. more...

(Submitter supplied) Global transcriptional profiling of Bacillus subtilis cells comparing wild-type to a (ccpN-yqfL) double mutant. Abstract of the associated publication (article accepted): The transcriptional regulator CcpN of Bacillus subtilis has been recently characterized as a repressor of two gluconeogenic genes, gapB and pckA, and of a small non-coding regulatory RNA, sr1, involved in arginine catabolism. Deletion of ccpN impairs growth on glucose and strongly alters the distribution of intracellular fluxes, rerouting the main glucose catabolism from glycolysis to the pentose phosphate (PP) pathway. more...

Characterization of PlcRa, a new PlcR-like regulator involved in oxidative stress response and cysteine metabolism during early stationary phase in Bacillus cereus

(Submitter supplied) PlcR, the major virulence transcriptional regulator in the Bacillus cereus group belongs to the RNPP quorum sensor family and is activated through interaction with the secreted heptapeptide PapR7 used as a signalling molecule. We identified using modeling analysis a structural homologue of PlcR, PlcRa, in B. cereus. Whole-genome comparative microarrays identified 119 genes (threshold >3) differentially expressed at the onset of stationary phase in a plcRa mutant. more...
