英文摘要
I explored the roles of electrostatic interactions in the movement of cytoplasmic domain of sarcoplasmic reticulum calcium pump by using a kinetic analysis of site-directed mutants. In this study, I found a linear relationship between logarithm of rate constant and square of the activity coefficient. This plot revealed that electrostatic interactions between domains act like a guide line of domain motion. This plot would provide a useful tool for quantification of electrostatic effects in the enzyme reactions.
