Binding of cAMP by an R subunit of PKA occurs in a cooperative fashion; i.e., binding of the first cAMP molecule to CNB-B lowers the Kd for binding of the second cAMP to CNB-A.

glutamate (E200) and arginine (R209) participate in binding of cAMP, which causes a conformational change in the loop that prevents binding of the loop to the C subunit.
