[[http://www.uniprot.org/uniprot/PSBF_THEVL PSBF_THEVL]] This b-type cytochrome is tightly associated with the reaction center 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.[HAMAP-Rule:MF_00643] [[http://www.uniprot.org/uniprot/PSBL_THEVL PSBL_THEVL]] This protein is a component of the reaction center 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.[HAMAP-Rule:MF_01379] [[http://www.uniprot.org/uniprot/CY550_THEVL CY550_THEVL]] Low-potential cytochrome c that plays a role in the oxygen-evolving complex of photosystem II (PSII). Binds to PSII in the absence of other extrinsic proteins; required for binding of the PsbU protein to photosystem II. In PSII particles without oxygen-evolving activity, maximal activity is restored only by binding of cytochrome c550, PsbU and the 33 kDa PsbO protein. 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.<ref>PMID:1314738</ref> <ref>PMID:8382523</ref> [[http://www.uniprot.org/uniprot/PSBE_THEVL PSBE_THEVL]] This b-type cytochrome is tightly associated with the reaction center of photosystem II (PSII).
