Short name: PQQ_synth_PqqF

Overlapping homologous superfamilies


Family relationships



In the subset of species that make coenzyme PQQ (pyrrolo-quinoline-quinone), this peptidase is found in the PQQ biosynthesis region and is thought to act as a protease on PqqA (IPR011725), a probable peptide precursor of the coenzyme. PQQ is required for some glucose dehydrogenases and alcohol dehydrogenases [PMID: 8526497].
