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.
