RG   Genoscope;
RL   Submitted (MAY-2006) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Involved in the binding and/or turnover of quinones at
CC       the Q(B) site of Photosystem II. {ECO:0000255|HAMAP-
CC       Rule:MF_01386}.
CC   -!- SUBUNIT: PSII consists of a core antenna complex that captures
CC       photons, and an electron transfer chain that converts photonic
CC       excitation into a charge separation. PSII forms dimeric complexes.
CC       {ECO:0000255|HAMAP-Rule:MF_01386}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC       {ECO:0000255|HAMAP-Rule:MF_01386}; Single-pass membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_01386}.
CC   -!- SIMILARITY: Belongs to the PsbX family. Type 1 subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01386}.
