RL   DNA Res. 10:137-145(2003).
CC   -!- FUNCTION: Involved in the binding and/or turnover of quinones at the
CC       Q(B) site of Photosystem II. {ECO:0000255|HAMAP-Rule:MF_01386}.
CC   -!- SUBUNIT: PSII consists of a core antenna complex that captures photons,
CC       and an electron transfer chain that converts photonic excitation into a
CC       charge separation. PSII forms dimeric complexes. {ECO:0000255|HAMAP-
CC       Rule:MF_01386}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01386}; Single-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01386}.
CC   -!- SIMILARITY: Belongs to the PsbX family. Type 1 subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01386}.
