CC   -!- FUNCTION: Required for ammonia secretion (By similarity). Also required
CC       for wild-type expression of ArfA. {ECO:0000250,
CC       ECO:0000269|PubMed:21802366}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Single-pass membrane
CC       protein {ECO:0000305}.
CC   -!- INDUCTION: Expressed equally at pH 5.5 and 7.2. Part of the arfA-arfB-
CC       arfC operon. {ECO:0000269|PubMed:21802366}.
CC   -!- DISRUPTION PHENOTYPE: No effect of a single gene deletion on growth at
CC       pH 7.0 nor of whole-operon deletion on growth at pH 4.6, 5.5 or 7.2. No
CC       effect of whole-operon deletion on growth in macrophages. Loss of
CC       expression of ArfA. {ECO:0000269|PubMed:21802366}.
CC   -!- SIMILARITY: Belongs to the ArfB membrane protein family. {ECO:0000305}.
