RT "Cloning and expression of pyrroloquinoline quinone (PQQ) genes from a
RT phosphate-solubilizing bacterium Enterobacter intermedium.";
RL Curr. Microbiol. 47:457-461(2003).
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}.
