| + | [https://www.uniprot.org/uniprot/PSBB_THEVL PSBB_THEVL] This protein binds multiple antenna chlorophylls and is part of the core of photosystem II (PSII). PSII is a light-driven water plastoquinone oxidoreductase, using light energy to abstract electrons from H(2)O, generating a proton gradient subsequently used for ATP formation. | ||
