P5511 Sigma

Protein Kinase A from bovine heart

≥0.4 units/μg protein, lyophilized powder

Synonym: Protein Kinase, 3′,5′-cyclic-AMP-dependent from bovine heart



Analysis Note

Protein determined by biuret.

Biochem/physiol Actions

Many 3′,5′-cyclic AMP dependent protein kinases have been reported. Structural studies (Traugh, J.A., et al., Meth. Enzymol., 38, 290 [1974]) show the presence of at least two subunits, the regulatory subunit and the catalytic subunit. When both units are linked together, the catalytic activity is inhibited. However, when the cyclic-AMP binds to the regulatory subunit, the catalytic subunit is released and can then catalyze the transfer of phosphate from ATP to various proteins.
