dc.description.abstractATP synthase catalyzes ATP synthesis by oxidative phosphorylation. With the unique mechanism and structure of ATP synthase, the energy transmission between the rotor and stator complex plays a vital role to maintain its proper function. Our previous study has discussed that upon γC87K mutation, a stronger interaction with βE381 could refrain the rotor complex from smooth spin, leading to insufficient energy coupling. In this study, we engineered alanine mutations to these residues to mimic a weaker rotor/stator interaction, and we found that multiple alanine mutation also impairs the enzyme performance. This research will add more pieces to understand the energy flow in ATP synthase.en_US
