F-type ATPases consist of two structural domains, F1 containing the extramembraneous catalytic core, and F0 which contains the membrane proton channel. This entry includes ATP synthase subunit delta from fungi (called epsilon in bacteria or chloroplast ATPase), which interacts with subunit C from F0 which is important for connecting the rotor of F1 (gamma subunit) to the rotor of F0 (C subunit). This entry represents the C-terminal alpha-helical domain which is likely to act as an inhibitor of ATPase activity [1-5].
