Glycogen synthase isolated from rabbit skeletal muscle as a D-form (synthase D2) is activated by a rat liver cytosolic protein differing from any of the known protein phosphatases (D2 activase). Although reversible by phosphorylation by cyclic AMP-dependent protein kinase, the activation is a result of limited proteolysis by D2 activase, which has been identified as the Ca2+-activated protease.
从兔骨骼肌中分离得到的糖原合酶D型(合酶D2)可被一种与任何已知蛋白磷酸酶不同的大鼠肝脏胞质蛋白(D2激活酶)激活。尽管可被环磷酸腺苷依赖性蛋白激酶磷酸化而逆转,但这种激活是D2激活酶有限蛋白水解的结果,D2激活酶已被鉴定为钙激活蛋白酶。
