Catabolite Activator Protein (CAP) Explanation

Catabolite activator proteins are trans-acting transcriptional activators, which are present in the form of homodimers in solutions. CAP's each subunit is made of a DNA-binding domain at the C-terminus and a ligand-binding domain at N-terminus. Two molecules of cAMP bind dimeric CAP with negative cooperativity.
