Thermodynamic Effects Of Phospholamban On Ca-Atpase Kinetics, Patrick L. Apopa Dec 2002

Thermodynamic Effects Of Phospholamban On Ca-Atpase Kinetics, Patrick L. Apopa

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Ca-ATPase of sarcoplasmic reticulum removes cytosolic calcium to promote muscle relaxation. In the heart, the Ca-ATPase is regulated by phospholamban, which inhibits the Ca-ATPase by decreasing Ca-ATPase calcium sensitivity. However, the kinetic and thermodynamic mechanisms of inhibition are not understood. The purpose of this research was to test the hypothesis that phospholamban regulates Ca-ATPase kinetics by increasing Ca-ATPase activation energy. The baculovirus-insect cell expression system was used to produce samples containing Ca-ATPase alone or Ca-ATPase with phospholamban. The temperature-dependence of Ca-ATPase activity and catalytic site density was measured in the absence and presence of phospholamban at sub-saturating calcium and …
