CC   -!- FUNCTION: Probable catalytic subunit of a protein translocase for
CC       flagellum-specific export, or a proton translocase involved in local
CC       circuits at the flagellum. May be involved in a specialized protein
CC       export pathway that proceeds without signal peptide cleavage (By
CC       similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + 4 H(+)(in) + H2O = ADP + 5 H(+)(out) + phosphate;
CC         Xref=Rhea:RHEA:57720, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=7.1.2.2;
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
CC       {ECO:0000305}.
