The sarcoplasmic reticulum of skeletal muscle contains anionic phospholipids as well as the zwitterionic phosphatidylcholine and phosphatidylethanolamine. Here we study the effects of anionic phospholipids on the activity of the Ca2+-ATPase purified from the membrane. Reconstitution of the Ca2+-ATPase into

Fibrates are used in biochemical and pharmacological studies as bioactive tools. Nevertheless, most studies have lacked information concerning the concentrations of fibric acids working inside tissues because a simple and sensitive method is not available for their quantitation. This study

Biochemistry, 31(26), 6023-6031 (1992-07-07)
The (Ca(2+)-Mg2+)-ATPase of sarcoplasmic reticulum was labeled with 4-(bromomethyl)-6,7-dimethoxycoumarin. It was shown that a single cysteine residue (Cys-344) was labeled on the ATPase, with a 25% reduction in steady-state ATPase activity and no reduction in the steady-state rate of hydrolysis
A P Starling et al.
The Biochemical journal, 304 ( Pt 2), 569-575 (1994-12-01)
On reconstitution of the Ca(2+)-ATPase of skeletal muscle sarcoplasmic reticulum into bilayers of dimyristoleoylphosphatidylcholine [di(C14:1)PC] or dinervonylphosphatidylcholine [di(C24:1)PC] the stoichiometry of Ca2+ binding changes from the usual two Ca2+ ions bound per ATPase molecule to one Ca2+ ion bound per
