Positive Control of Energy Metabolism

Function mediated by cAMP receptor protein/catabolite gene activator protein.

Positive control of energy metabolism is effected through a process otherwise known as catabolite repression, which results in a deemphasis on the use of non-preferred carbon sources by especially bacteria cells. In the classic example, glucose is used preferentially to lactose (see Lac operon).
