CAP
(= catabolite gene activator protein)
Protein from E. coli that regulates the expression of genes for the use of alternative carbon sources if glucose is not available. For example, CAP and the lactose repressor protein act together to enable lactose to be utilized. If glucose is present CAP will not bind to DNA, in the absence of glucose cAMP levels rise, CAP binds cAMP, undergoes a conformational change, and is then capable of binding to DNA and promoting transcription of derepressed genes.
