Crystallization studies of cAMP-dependent protein kinase. Crystals of catalytic subunit diffract to 3.5 A resolution

The catalytic subunit of cAMP-dependent protein kinase from porcine heart has been crystallized in several different crystal forms. One of these forms diffracts to 3.5 A resolution. It is in monoclinic space group P2(1) with a = 64.24 A, b = 143.58 A, c = 48.40 A, alpha = gamma = 90 degrees and beta = 106.9 degrees.
