Lumenal processes under pH regulation. (1) Light-induced expansion of the lumen volume facilitating plastocyanin migration and (2) enhancement of ATP synthase activity; (3) Light-induced activation of VDE and PsbS by protonation for photoprotection; (4) Deg oligomerization for PSII repair; and (5) induction of photosynthetic control via cyt b6f.
