    A comparative study of the rat heart sarcolemmal Ca2+-dependent ATPase and myosin ATPase

    In order to gain some information regarding Ca2+-dependent ATPase, the enzyme was purified from cardiac sarcolemma and its properties were compared with Ca2+-ATPase activity of myosin purified from rat heart. Bot...

    Phosphorylation of aortic plasma membranes by protein kinase C

    Incubation of plasma membranes isolated from bovine aorta with either 0.5 mM CaCl2 or with a phorbol ester (1 µM phorbol 12,13-dibutyrate) and phosphatidylserine in an EGTA-containing buffer resulted in the phosp...

    Characterization of the purified rat heart plasma membrane Ca2+/Mg2+ ATPase

    The purified Ca2+/Mgu2+ ATPase from rat heart plasma membrane was activated by Ca2+ and Mg2+ with Ka values of 1.47 mM and 2.51 mM, respectively; other divalent cations also activated the enzyme but to a lesser e...

    Purification and composition of Ca2+/Mg2+ ATPase from rat heart plasma membrane

    The Ca2+/Mg2+ ATPase, which is activated by millimolar concentrations of Ca2+ or Mg2+, was solubilized from rat heart plasma membrane by employing lysophosphatidylcholine, CHAPS, Nal, EDTA and Tris-HCI at pH 7.4....

    Comparison of an endogenous protein kinase C substrate in rat aorta with rat brain MARCKS

    We have compared the properties of a rat aorta-derived protein kinase C substrate (p75) with those of 80 kDa kinase C substrates from rat brain (MARCKS) and rabbit aorta (p80). Rat aortic p75 appeared to be cl...
