Interquinone Q<sub>A</sub><sup>-</sup> → Q<sub>B</sub> electron-transfer (ET) in isolated photosystem II reaction centers (PSII-RC) is protein-gated. The temperature-dependent gating frequency "k" is described by the Eyring equation till levelling off at T ≥ 240 °K. Although central to photosynthesis, the gating mechanism has not been resolved and due to experimental limitations, could not be explored in vivo. Here we mimic the temperature dependency of "k" by enlarging V<sub>D1-208</sub>, the v ...[more]
