RT   "bptA (bbe16) is essential for the persistence of the Lyme disease
RT   spirochete, Borrelia burgdorferi, in its natural tick vector.";
RL   Proc. Natl. Acad. Sci. U.S.A. 102:6972-6977(2005).
CC   -!- FUNCTION: Virulence-associated protein essential for survival of the
CC       bacterium within the tick host and therefore within the natural life
CC       cycle of the Lyme disease spirochete. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the BptA family. {ECO:0000305}.
