These results suggested that in chloroplast ATP synthase, both the N-terminus and C-terminus of the ε subunit show importance in regulation of the ATPase activity. Furthermore, the N-terminus of the ε subunit is more important for its interaction with γ and some CF〓 subunits, and crucial for the blocking of proton leakage. Compared with the ε subunit from E. coli, the chloroplast ε subunit is more sensible to N-terminal or Cterminal truncations.
