The calmodulin-stimulated ATPase of maize coleoptiles is a 140,000 Mr polypeptide. In the present study, formation of a phosphorylated intermediate by the enzyme is demonstrated. Phosphorylation is sensitive to chasing with unlabelled ATP and to hydroxylamine; lanthanum enhances its intensity while calmodulin enhances phosphorylation in the presence of… CONTINUE READING
