Popis: Calmodulin-dependent protein kinase III (CaM kinase III) phosphorylates and thereby inactivates eukaryotic elongation factor-2 (EF-2). This enzyme, purified to homogeneity from either rabbit reticulocytes or rat pancreas, had similar properties: it migrated with an apparent M(r) of 140,000 by gel filtration, was comprised of a major polypeptide of M(r) 95,000 by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and had a high affinity for CaM (half-maximal activation
