Stabilization, purification and crystallization of catalytic subunit of cAMP-dependent protein kinase from bovine heart.
The catalytic subunit of cAMP-dependent protein kinase purified from bovine heart was significantly stabilized by non-ionic detergents. Freezing and thawing did not cause a significant decrease in the enzyme activity in the presence of 0.1% Tween 80. A very convenient method for purification and crystallization of the catalytic subunit was also described.
