cAMP-dependent protein kinase from Creative Enzymes

cAMP is required to activate this enzyme. The inactive holoenzyme of cAMP-dependent protein kinase is a tetramer composed of two regulatory (R) and two catalytic (C) subunits. cAMP causes the dissociation of the inactive holoenzyme into a dimer of regulatory subunits bound to four cAMP molecules and two free monomeric catalytic subunits [i.e. R2C2 + 4 cAMP = R2(cAMP)4 + 2 C]
