Figure 3. Distinct redox active statuses in the stroma and the
lumen.
Light-dependent thiol/disulfide-regulated (A) stromal proteins are
considered to be in their active form when they are reduced. Conversely,
(B,C) lumenal proteins are considered to be in their active form when
they become oxidized. The proposed oxidation models are: (B) oxygen
(O2) and (C) LTO1.
