Carbon catabolite repression, or simply catabolite repression, is an important part of global control system of various bacteria and other micro-organisms. Catabolite repression allows bacteria to adapt quickly to a preferred (rapidly metabolisable) carbon and energy source first. This is usually achieved through inhibition of synthesis of enzymes...

Inducible enzyme systems in some microorganisms (such as the lac operon> lacoperon) that are repressed when a more favoured carbon source, such as glucose, is available. Repression in E. coli is partially relieved if cAMP is bound to the cAMP-catabolite activator protein (cAMP receptor protein; CRP) that binds to DNA upstream of the repressed operon concerned. Catabolite repression (of the respiratory system) is seen in yeast in high glucose concentrations, though the mechanism is different.
