| 摘要 |
The invention provides a modified pyrrolo-quinoline quinone glucose dehydrogenase (PQQGDH) enzyme protein which is modified to have a substrate specificity to glucose. The modified PQQGDH of the invention exhibits a high substrate specificity compared to the wild type PQQGDH, thus is useful in determining glucose concentration in clinical assays and food analyses. A gene coding for the modified PQQGDH and a glucose sensor comprising the modified PQQGDH are also disclosed.
