CC   -!- FUNCTION: May be involved in the transport of PQQ or its precursor to
CC       the periplasm, in association with PQQ biosynthesis, but is not
CC       absolutely required for this synthesis.
CC   -!- PATHWAY: Cofactor biosynthesis; pyrroloquinoline quinone biosynthesis.
CC   -!- SIMILARITY: Belongs to the PqqB family. {ECO:0000305}.
