Evidence for a membrane-bound pyrroloquinoline quinone-linked glucose dehydrogenase in Acetobacter diazotrophicus [PDF]

, 2022
Acetobacter diazotrophicus possesses a pyrroloquinoline quinone-linked glucose dehydrogenase (PQQ-GDH). The enzyme seemingly belongs to the type II PQQ-GDH enzymes and, at least under the culture conditions tested, the organism synthesizes enough PQQ to ...
