Soluble quinoprotein glucose dehydrogenase (EC 1.1.99.35, soluble glucose dehydrogenase, sGDH, glucose dehydrogenase (PQQ-dependent)) is an enzyme with systematic name D-glucose:acceptor oxidoreductase.[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction
- D-glucose + acceptor [math]\displaystyle{ \rightleftharpoons }[/math] D-glucono-1,5-lactone + reduced acceptor
This soluble periplasmic enzyme contains PQQ as prosthetic group, and is bound to a calcium ion. Electron acceptor is not known.
