β-Lactamase(Amp) is produced by some bacteria, providing resistance against penicilins and so on. Theβ-Lactamase hydrolyzes β-lactam's conservative ring region, deactivating the antibiotic, and it can be use for the treatment of bacterial infection.
In our project, β-Lactamase is used to catalyze the hydrolysis of penicillin to penicillinoic acid, leading to current changes to be detected using A3 electrode system. We can dissect β-Lactamase between Gly196 and Leu198, for this is opposite to the active site; meanwhile we can acquire a more active and metabolically stable pattern by introducing a mutation M182T, which disrupts an inactive molten-globule intermediate of β-Lactamase.
