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_01388}.
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_01388}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000255|HAMAP-
CC Rule:MF_01388}; Single-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01388}.
CC -!- SIMILARITY: Belongs to the PsbX family. Type 2 subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01388}.
