Gene Regulation - Nicholls State University
... CAP is a general activator protein. It activates the expression of many genes in the cell when ATP levels are low. When ATP levels are low, ADP levels are high, and some of the ADP is converted to cyclic AMP (cAMP) by adenyl cyclase. High levels of cAMP is a general indicator of low energy levels in ...
