some of the factors leading to phosphorylation under these conditions include 1 ) partial activation of myosin light chain kinase with each stimulus , 2 ) a slow rate ( t1/2 = 1 s ) of inactivation of the kinase activity , and 3 ) a very slow rate of dephosphorylation by myosin light chain phosphatase .
