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. {ECO:0000255|HAMAP-Rule:MF_00656}.
CC   -!- PATHWAY: Cofactor biosynthesis; pyrroloquinoline quinone biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00656}.
CC   -!- SIMILARITY: Belongs to the PqqA family. {ECO:0000255|HAMAP-
CC       Rule:MF_00656}.
