CC   -!- FUNCTION: Unknown. Resembles PsbF, one of the subunits of the
CC       photosystem II reaction center. However, it encodes asparagine rather
CC       than histidine at the site PsbF uses to bind heme.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the PsbE/PsbF family. {ECO:0000305}.
