IntEnz Enzyme Nomenclature


Accepted name:
cAMP-dependent protein kinase
Other names:
protein kinase A
Systematic name:
ATP:protein phosphotransferase (cAMP-dependent)



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]. Formerly EC
