CC   -!- FUNCTION: Functions as a PqqA binding protein and presents PqqA to
CC       PqqE, in the pyrroloquinoline quinone (PQQ) biosynthetic pathway.
CC       {ECO:0000255|HAMAP-Rule:MF_00655}.
CC   -!- PATHWAY: Cofactor biosynthesis; pyrroloquinoline quinone biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00655}.
CC   -!- SUBUNIT: Monomer. Interacts with PqqE. {ECO:0000255|HAMAP-
CC       Rule:MF_00655}.
CC   -!- SIMILARITY: Belongs to the PqqD family. {ECO:0000255|HAMAP-
CC       Rule:MF_00655}.
