The calcium transport mechanism of cardiac sarcoplasmic reticulum (SR) is (SR) is regulated by a phosphoregulatory mechanism involving the phosphorylation-dephosphorylation of an integral membrane component, termed phospholamban. Phospholamban, a 27,000 Da proteolipid, contains phosphorylation sites
Coupling of Ca2+ transport to ATP hydrolysis in isolated sarcoplasmic reticulum vesicles has been studied following pulsed additions of either ATP or Ca2+. ATP was infused as a pulse into medium, whose free Ca2+ concentration was maintained constant at saturating levels by a calciumstat procedure, u
