Outline of Final Research Achievements |
Enzymes of the ATPase family accomplish various functions using ATP hydrolysis energy, which is widely used in all living organisms. All proteins including this important ATPase, proceed their own reaction (function) along with the structural change. So as to understand the ATPase mechanism commonly underlying over ATPase family, the structural change of ATPase were investigated. The structural change of ATPase comprises the three different conformational changes: by ATP binding, by ATP hydrolysis, and by product release. To obtain the whole mechanism, all the steps need to be clarified. The beta subunit of F1-ATPase which has been studied extensively, was selected as representation of the ATPase family protein. Using the MD simulations, all the steps of the conformational change in the beta subunit were revealed. The mechanism obtained here was compared with that of other ATPases.
