[[http://www.uniprot.org/uniprot/PSBL_CYACA PSBL_CYACA]] One of the components of the core complex of photosystem II (PSII). 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. This subunit is found at the monomer-monomer interface and is required for correct PSII assembly and/or dimerization. [[http://www.uniprot.org/uniprot/PSBH_CYACA PSBH_CYACA]] One of the components of the core complex of photosystem II (PSII), required for its stability and/or assembly. 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. [[http://www.uniprot.org/uniprot/YCF12_CYACA YCF12_CYACA]] A core subunit of photosystem II (PSII). [[http://www.uniprot.org/uniprot/PSBB_CYACA PSBB_CYACA]] 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. [[http://www.uniprot.org/uniprot/PSBA_CYACA PSBA_CYACA]] 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/PsbA) reaction center heterodimer binds P680, the primary electron donor of PSII as well as several subsequent electron acceptors.[HAMAP-Rule:MF_01379] [[http://www.uniprot.org/uniprot/C550B_CYACA C550B_CYACA]] Low-potential cytochrome c that plays a role in the oxygen-evolving complex of photosystem II (PSII). Unlike Synechococcus vulcanus it does not bind by itself to PSII, but requires all extrinsic members of the OEC. [[http://www.uniprot.org/uniprot/PSBF_CYACA PSBF_CYACA]] This b-type cytochrome is tightly associated with the reaction center of photosystem II (PSII). 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. [[http://www.uniprot.org/uniprot/PSBC_CYACA PSBC_CYACA]] One of the components of the core complex of photosystem II (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] [[http://www.uniprot.org/uniprot/PSBJ_CYACA PSBJ_CYACA]] One of the components of the core complex of photosystem II (PSII). 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. [[http://www.uniprot.org/uniprot/PSBT_CYACA PSBT_CYACA]] Seems to play a role in the dimerization of PSII. [[http://www.uniprot.org/uniprot/PSBU_CYACA PSBU_CYACA]] 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). Does not bind by itself to PSII; it requires all other members of the OEC. [[http://www.uniprot.org/uniprot/PSBI_CYACA PSBI_CYACA]] One of the components of the core complex of photosystem II (PSII), required for its stability and/or assembly. 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. [[http://www.uniprot.org/uniprot/PSBD_CYACA PSBD_CYACA]] 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/PsbA) reaction center heterodimer binds P680, the primary electron donor of PSII as well as several subsequent electron acceptors. D2 is needed for assembly of a stable PSII complex. [[http://www.uniprot.org/uniprot/PSBK_CYACA PSBK_CYACA]] One of the components of the core complex of photosystem II (PSII). 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. [[http://www.uniprot.org/uniprot/PSBE_CYACA PSBE_CYACA]] This b-type cytochrome is tightly associated with the reaction center of photosystem II (PSII). 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.
