2.7.11.11 cAMP-dependent protein kinaseIUBMB Comments
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].

more than 2fold increased activity after 15 min at 0.1 nM
-
cAMP
dependent on, acts synergistically with cGMP, binding site domain structure on the regulatory subunit RII
cAMP
-
dependent on, activates the enzyme by partly dissociating the regulatory and the catalytic subunits, determination and analysis of the mechanism, the substrate plays a differential role in activation of type I versus type II holoenzyme
cAMP
-
dependent on, competitive to regulatory subunit RIalpha, at low concentration the activation of PKA type I, but not of PKA type II, by cAMP is accelerated by the peptide or protein substrate by increased dissociation of subunits Calpha and RIalpha, cAMP has low effect on RII/PKA type II, overview
cAMP
-
dynamics of the binding domain structure, molecular binding mechanism, overview
cAMP
-
exposure of mitochondria to cAMP results in enhanced catalytic subunit catalytic activity. Upon binding of cAMP to the regulatory subunits, the catalytic subunits are released and are thus free to catalyze the phosphorylation of an array of proteins, But cAMP fails to promote R subunit degradation by beta-catenin
cAMP
-
activation of protein kinase A involves the synergistic binding of cAMP to two cAMP binding sites on the inhibitory R subunit, causing release of the C subunit, which subsequently can carry out catalysis
cAMP
-
binds to the 2 catalytic subunits and activates via dissociation of the regulatory dimer
cAMP
-
dependent on
cAMP
-
intracellular amount is controlled by the stimulating steroid hormone adrenocorticotropin ACTH in the adrenal cortex increasing PKA enzyme activity, cAMP induces MKP-1 mRNA and protein expression
cAMP
-
dependent on, competitive to regulatory subunit RIalpha, at low concentration the activation of PKA type I, but not of PKA type II, by cAMP is accelerated by the peptide or protein substrate by increased dissociation of subunits Calpha and RIalpha, cAMP has low effect on RII/PKA type II, overview
cAMP
-
dependent on, degree of enzyme activation by cAMP or cGMP depends on the substrate
cAMP
-
required for activity, activation is mediated by binding of cAMP to the regulatory subunits, causing release of the catalytic subunits
cAMP
-
dependent on, structural basis of activation mechanism, binding induces conformational changes in the regulatory subunit RIalpha
cAMP
binding of 2 cAMP molecules to each regulatory subunit alters its affinity for the catalytic subunit, resulting in release of the active catalytic subunit; binding of 2 cAMP molecules to each regulatory subunit alters its affinity for the catalytic subunit, resulting in release of the active catalytic subunit
cAMP
-
each monomer of the tetrameric enzyme contains 2 bindig sites A and B for cAMP, binding involves Arg230 of domain A and Arg359 in domain B of regulatory subunit RIIbeta, cAMP binding releases the catalytic subunits
cGMP
-
activates, degree of enzyme activation by cAMP or cGMP depends on the substrate
