Outline of Final Research Achievements

The role of electrostatic interactions in and the effects of the lipid environment on the reaction mechanisms on sarcoplasmic reticulum Ca2+-ATPase were explored. The experiments using the Ca2+-ATPase buried into nanodiscs which contained various lipid contents revealed that the not only electrostatic interactions between protein and lipids but also steric interactions between them have important for function of the pump. This study succeeded clearly to divide the effects of the lipid environment between electrostatic interactions and steric interactions.
