Protein Variants
| Protein Variants | Comment | Organism |
|---|---|---|
| C188S | the activity of the mutant is much lower than that of the native enzyme | Bordetella bronchiseptica |
| G74C | the activity of the mutant is much lower than that of the native enzyme | Bordetella bronchiseptica |
| G74C/C188G | the mutant has a 5.6fold increase in activity compared with the G74C/C188S mutant | Bordetella bronchiseptica |
| G74C/C188S | the mutant has 18000fold reduced activity compared to the wild type enzyme, the (S)-selective arylmalonate decarboxylase variant has a 220fold improved activity in the production of (S)-naproxen with excellent enantioselectivity (99% ee) | Bordetella bronchiseptica |
| G74C/M159L/C188G | the mutant shows a 210fold increase in activity compared with the G74C/C188S mutant | Bordetella bronchiseptica |
| Y48F/G74C/C188G | the mutant shows a 23fold increase in activity compared with the G74C/C188S mutant | Bordetella bronchiseptica |
| Y48F/G74C/M159L/C188G | the mutant shows a 920fold activity increase relative to the G74C/C188S mutant | Bordetella bronchiseptica |
