Catabolite activator protein (CAP; also known as cAMP receptor protein, CRP) is a trans-acting transcriptional activator that exists as a homodimer in solution. Each subunit of CAP is composed of a ligand-binding domain at the N-terminus (CAP , residues 1–138) and a DNA-binding domain at the C-terminus (DBD, residues 139–209).
