Probing the regulatory effects of specific mutations in three major binding domains of the pleiotropic regulator CcpA of Bacillus subtilis

ABSTRACT: Study the effect of single amino acid point mutations in CcpA at the transcriptome level. Cells were grown in LB with or without 1% glucose and harvested at an OD600 of 0.3 (early exponential phase). Bacillus subtilis strain ccpA::spec carrying pHT304 (empty plasmid), pWH_ccpA_M17R, pWH_ccpA_T62H, or pWH_ccpA_R304W were grown in LB with or without 1% glucose. The control in the microarray study was the strain Bacillus subtilis ccpA::spec carrying pWH_ccpA-wt. All Bacillus subtilis cultures were harvested in the early exponential growth phase at an OD600 of 0.3 from 100 ml culture. Two independent cultures of each strain per growth condition (+/- glucose) and a technical replicate (dye-swap) were used. Please note that '[A}' and '{B}' channels (in the raw data *slide.txt files) correspond t
