G423D | site-directed mutagenesis, the mutant shows no activity compared to the wild-type enzyme | Penicillium amagasakiense |
G423D | site-directed mutagenesis, the mutants containing the mutation G423D leads to quadruple mutants that are not able to reconstitute. The mutant enzymes displays a dramatic decrease in activity compared to thré wild-type enzyme | Penicillium amagasakiense |

K23E | site-directed mutagenesis | Penicillium amagasakiense |
K260E. | site-directed mutagenesis | Penicillium amagasakiense |
K424E | site-directed mutagenesis, the single mutation results in a significant increase in the current density which becomes 2.4 fold higher than the current obtained for the wild-type | Penicillium amagasakiense |
K424I | site-directed mutagenesis, the mutation does not significantly affect the enzyme activity | Penicillium amagasakiense |
K48/50E | site-directed mutagenesis | Penicillium amagasakiense |
additional information | for use on electrode surfaces, the key amino acid at the entrance of the active site of glucose oxidase from Penicilium amagasakiense, Lys424, Gln75, Gln184, and Gly423, are redesign by nonactive site mutations, leading to enzymatic anodes with 2.4fold higher current densities, making the biosensor more effective. 424 is the key position | Penicillium amagasakiense |
Q184E | site-directed mutagenesis | Penicillium amagasakiense |
