in the present study , we utilized a highly purified catalytic subunit of a type-2 , skeletal muscle phosphoprotein phosphatase ( protein phosphatase 2a ) and a glycerinated smooth muscle preparation to determine if myosin dephosphorylation , in the presence of saturating calcium and calmodulin , would cause relaxation of contracted uterine smooth muscle .
