✦ Synopsis
Membranes isolated from pea buds contain protein-kinase activity which is greatly activated by low concentrations of calcium ions. This paper describes a simple purification of this enzyme with a novel means of detecting enzyme activity by Western blotting. The purified enzyme appears to autophosphorylate primarily on serine residues, is activated by bovine calmodulin and additional evidence from phase partitioning indicate most of this enzyme to be located in the plasma membrane.
