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.

从这些实验结果中可以看出：（1）叶绿体ATP合酶ε-亚基的N端和C端对于其功能的发挥都很重要；（2）ε亚基N端和C端氨基酸在抑制ATP水解和堵塞质子泄漏两个功能上起着不同的作用；（3）与细菌ATP合酶相比，叶绿体ATP合酶ε亚基N端和C端的缺失对其功能的影响更为显著。
