Enzyme Information

2.7.11.11
cAMP-dependent protein kinase.
based on mapping to UniProt P05132
ATP + a protein = ADP + a phosphoprotein.
-!- 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. R(2)C(2) + 4 cAMP = R(2)(cAMP)(4) + 2 C). -!- Formerly EC 2.7.1.37.
