Calmodulin-dependent protein kinase II was purified to apparent homogeneity with a high yield from the total calmodulin-binding protein fraction of bovine cardiac muscle in a single step by gel filtration column chromatography. This procedure is simple and suitable for adaptation to large scale preparations. The purified calmodulin-dependent protein kinase has a specific enzymic activity of 2.4 mumol/min/mg when mixed histone was used as a substrate. The preparation of enzyme appears to be homogeneous when examined by SDS-PAGE. The molecular weight of the enzyme was determined to be 570 kDa by gel filtration. SDS-PAGE of the enzyme subunit showed a single protein band with an apparent molecular weight of 56 kDa. These results suggest that the calmodulin-dependent protein kinase II from bovine heart is composed of 10 identical subunits. Anti-peptide antibody raised against multifunctional calmodulin-dependent protein kinase II from rat brain showed a single immunoreactive band of 56 kDa on Western blot. These results suggested that bovine cardiac muscle calmodulin-dependent protein kinase could resemble the brain isozyme. Calmodulin-dependent protein kinase II undergoes autophosphorylation with a maximal incorporation of 1 mol of phosphate per mol of the subunit of the enzyme and the autophosphorylated enzyme remains active in the absence of Ca2+ and calmodulin. The concentration of Ca2+ required for the activation of calmodulin-dependent protein kinase II depends on the level of calmodulin in the reaction.
