[[http://www.uniprot.org/uniprot/PSBL_THEEB PSBL_THEEB]] Required for PSII activity (By similarity). [[http://www.uniprot.org/uniprot/YCF12_THEEB YCF12_THEEB]] A core subunit of photosystem II (PSII).[HAMAP-Rule:MF_01329] [[http://www.uniprot.org/uniprot/PSBB_THEEB PSBB_THEEB]] One of the components of the core complex of photosystem II (PSII). It binds chlorophyll and helps catalyze the primary light-induced photochemical processes of PSII. PSII is a light-driven water:plastoquinone oxidoreductase, using light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation.[HAMAP-Rule:MF_01495]<ref>PMID:20558739</ref> <ref>PMID:21367867</ref> <ref>PMID:25006873</ref>  [[http://www.uniprot.org/uniprot/PSBA1_THEEB PSBA1_THEEB]] This is one of the two reaction center proteins of photosystem II. [[http://www.uniprot.org/uniprot/PSBX_THEEB PSBX_THEEB]] Involved in the binding and/or turnover of quinones at the Q(B) site of Photosystem II.<ref>PMID:11230572</ref>  [[http://www.uniprot.org/uniprot/CY550_THEEB CY550_THEEB]] Low-potential cytochrome c that plays a role in the oxygen-evolving complex of photosystem II. It is not essential for growth under normal conditions but is required under low CO(2) concentrations.[HAMAP-Rule:MF_01378] [[http://www.uniprot.org/uniprot/PSBO_THEEB PSBO_THEEB]] MSP binds to a putative Mn-binding protein and keeps 2 of the 4 Mn-atoms associated with PSII (By similarity). [[http://www.uniprot.org/uniprot/PSBF_THEEB PSBF_THEEB]] This b-type cytochrome is tightly associated with the reaction center of photosystem II and possibly is part of the water-oxidation complex (By similarity).[HAMAP-Rule:MF_00643] [[http://www.uniprot.org/uniprot/PSBC_THEEB PSBC_THEEB]] One of the components of the core complex of photosystem II (PSII). It binds chlorophyll and helps catalyze the primary light-induced photochemical processes of PSII. PSII is a light-driven water:plastoquinone oxidoreductase, using light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation.[HAMAP-Rule:MF_01496]<ref>PMID:20558739</ref> <ref>PMID:21367867</ref> <ref>PMID:25006873</ref> [[http://www.uniprot.org/uniprot/PSBJ_THEEB PSBJ_THEEB]] This protein is a component of the reaction center of photosystem II (By similarity). [[http://www.uniprot.org/uniprot/PSBT_THEEB PSBT_THEEB]] Seems to play a role in the dimerization of PSII.<ref>PMID:15653799</ref>  [[http://www.uniprot.org/uniprot/PSBU_THEEB PSBU_THEEB]] Stabilizes the structure of photosystem II oxygen-evolving complex (OEC), the ion environment of oxygen evolution and protects the OEC against heat-induced inactivation (By similarity).[HAMAP-Rule:MF_00589] [[http://www.uniprot.org/uniprot/PSBI_THEEB PSBI_THEEB]] This protein is a component of the reaction center of photosystem II.[HAMAP-Rule:MF_01316] [[http://www.uniprot.org/uniprot/PSBZ_THEEB PSBZ_THEEB]] Controls the interaction of photosystem II (PSII) cores with the light-harvesting antenna. May also aid in binding of PsbK, Ycf12 and the oxygen-evolving complex to PSII, at least in vitro.<ref>PMID:17967798</ref>  [[http://www.uniprot.org/uniprot/PSBK_THEEB PSBK_THEEB]] This protein is a component of the reaction center of photosystem II.[HAMAP-Rule:MF_00441] [[http://www.uniprot.org/uniprot/PSBE_THEEB PSBE_THEEB]] This b-type cytochrome is tightly associated with the reaction center of photosystem II and possibly is part of the water-oxidation complex.[HAMAP-Rule:MF_00642]
[https://www.uniprot.org/uniprot/PSBA1_THEVB PSBA1_THEVB] Photosystem II (PSII) is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. The D1/D2 (PsbA/PsbD) reaction center heterodimer binds P680, the primary electron donor of PSII as well as several subsequent electron acceptors.[HAMAP-Rule:MF_01379]<ref>PMID:20558739</ref> <ref>PMID:21367867</ref> <ref>PMID:25006873</ref>
