Hinoprotein glukoza dehidrogenaza (EC 1.1.5.2, membranska glukozna dehidrogenaza, mGDH, glukozna dehidrogenaza (PQQ-zavisna), glukozna dehidrogenaza (pirolohinolin-hinon), hinoproteinska D-glukozna dehidrogenaza) je enzim sa sistematskim imenom D-glukoza:ubihinon oksidoreduktaza.[1][2][3][4][5][6][7][8][9][10] Ovaj enzim katalizuje sledeću hemijsku reakciju
- D-glukoza + ubihinon D-glukono-1,5-lakton + ubihinol
Ovaj integralni membranski protein sadrži PQQ kao prostetičku grupu. On takođe sadrži vezan ubihinon i Mg2+ ili Ca2+. Elektronski akceptor je membranski ubihinon.
