Pirolohinolin hinon (PQQ) je redoks kofaktor kod bakterija .^[5]^[6]^[7]^[8] PQQ je prostetička grupa u metanolnoj dehidrogenazi metilotrofa, kao što je bakterijska vrsta Acetobacter.^[9]

Enzimi koji sadrže PQQ se nazivaju hinoproteini. Glukozna dehidrogenaza, jedan od hinoproteina, se koristi kao glukozni senzor. Utvrđeno je da PQQ stimuliše rast bakterija.^[10] Osim toga, on ima antioksidansno i neuroprotektivno dejstvo.^[11]

PQQ biosinteza kod bakterija počinje sa proteinskom biosintezom kojom se formira kratki peptid, PqqA, na ribozomu. Svi atomi u PQQ su izvedeni iz glutaminske kiseline i tirozina u PqqA, koji se povezuju posrestvom radikalnog SAM enzima PqqE.^[12]
