General description
Native PKA catalytic subunit purified from bovine heart. The catalytic subunit of PKA dissociates from the PKA holoenzyme following binding of cAMP to the PKA regulatory subunits and phosphorylates target proteins at serine and/or threonine within the recognition motif, Arg-Arg-X-Ser*-X. The purified monomeric catalytic subunit does not require cAMP for activation and is suitable for studies of PKA phosphorylation in vitro with purified substrates or following its introduction into intact cells or cell extracts.
