CC   -!- FUNCTION: Required for coenzyme pyrroloquinoline quinone (PQQ)
CC       biosynthesis. PQQ is probably formed by cross-linking a specific
CC       glutamate to a specific tyrosine residue and excising these residues
CC       from the peptide (By similarity). {ECO:0000250}.
CC   -!- PATHWAY: Cofactor biosynthesis; pyrroloquinoline quinone biosynthesis.
CC   -!- SIMILARITY: Belongs to the PqqA family. {ECO:0000305}.
