CC   -!- FUNCTION: Required for sporulation. {ECO:0000269|PubMed:12662922}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Single-pass membrane
CC       protein {ECO:0000305}.
CC   -!- INDUCTION: Expression controlled by a sigma-E-regulated promoter which
CC       needs the sigma-E factor for the binding of the RNA polymerase and
CC       subsequent transcription. {ECO:0000269|PubMed:12662922}.
