Escherichia coli is unable to produce pyrroloquinoline quinone (PQQ). [PDF]

Microbiology, 1997
Many bacteria can synthesize the cofactor pyrroloquinoline quinone (PQQ), a cofactor of several dehydrogenases, including glucose dehydrogenase (GCD). Among the enteric bacteria, Klebsiella pneumoniae has been shown to contain the genes required for PQQ biosynthesis.
