2.7.1.127 | phosphoprotein |
phosphorylation of enzyme by calmodulin kinase II and protein kinase C added together results in a maximal 60-70fold activation, distinct sites are phosphorylated independently by both protein kinases, prevented by the CaM kinase II inhibitors KN-93, KN-62 and the protein kinase C inhibitor calphostin C |

2.7.1.127 | phosphoprotein |
phosphorylation of Thr-311 by CaM kinase II results in 8-10fold enzyme activation in the presence of 0.01 mM free Ca2+ and 0.002 mM calmodulin and in a 25fold increase in sensitivity to the Ca2+/calmodulin complex |
