we have shown that the phosphorylation of smooth muscle regulatory myosin light chain ( l20 ) with myosin light chain kinase ( mlck ) produces faster moving bands ( gmp1 : heterodimer myosin with 1 unphosphorylated l20 and 1 mono-phosphorylated l20 , gmp2 : homodimer myosin with 2 mono-phosphorylated l20s ) on native pyrophosphate polyacrylamide gel electrophoresis ( pp1 page ) ( j. biochem . 100 , 259-268 , 1986 ; j. biochem . 100 , 1681-1684 , 1986 ) .
