Protein: Catabolite control protein A (Glucose-resistance amylase regulator) (P25144)
Organism: Bacillus subtilis (strain 168)
Function: Global transcriptional regulator of carbon catabolite repression (CCR) and carbon catabolite activation (CCA), which ensures optimal energy usage under diverse conditions. Interacts with either P-Ser-HPr or P-Ser-Crh, leading to the formation of a complex that binds to DNA at the catabolite-response elements (cre). Binding to DNA allows activation or repression of many different genes and operons.
