Comparison of Myosin ATPase Activities from Red Muscle and White Muscle

Abstract
|
|
|
|
Myosin were prepared from red muscle and white muscle, and their ATPase activities were compared. Ca-ATPase activity of bovine myosin from red muscle was higher than that of myosin from white muscle, while Ca-ATPase activity of chicken myosin from red muscle differed hardly from that of myosin from white muscle. Also EDTA-ATPase activity of bovine red muscle myosin was higher than that of white muscle myosin, although EDTA-ATPase activity of chicken mysoin from red muscle differed hardly from that of white muscle myosin. When myosins were treated with trypsin, bovine myosin from white muscle was hydrolysed more easily than red muscle myosin was. Chicken myosin from red muscle, however, was hydrolysed by trypsin more easily than white muscle myosin was.
