Molecular basis of plastoquinone reduction in plant cytochrome b<sub>6</sub>f.
Nature plants 20241003 11
A multi-subunit enzyme, cytochrome b<sub>6</sub>f (cytb<sub>6</sub>f), provides the crucial link between photosystems I and II in the photosynthetic membranes of higher plants, transferring electrons between plastoquinone (PQ) and plastocyanin. The atomic structure of cytb<sub>6</sub>f is known, but its detailed catalytic mechanism remains elusive. Here we present cryogenic electron microscopy structures of spinach cytb<sub>6</sub>f at 1.9 Å and 2.2 Å resolution, revealing an unexpected orientat ...[more]
