The role of metal ions as activators of arginase hydrolyzing arginine were studied. The metal ion is assumed to form a complex with arginine and to promote the enzymatic reaction. The activating ability of the metal ion appears to be governed by the chelating ability and/or the coordination numbers
The effects of divalent metals, metal chelators (EDTA, EGTA) and sodium dodecyl sulfate were investigated on the phosphatase activity of isolated bovine brain calcineurin assayed in the absence (called intrinsic) and presence of calmodulin. Intrinsic phosphatase was increased by Mn2+, was unaffected
