   1.14.13.210 | L380I |
site-directed mutagenesis, the mutant shows unaltered activity with 4-nitrophenol compared to the wild-type enzyme |
-, 735475 |
| 1.14.13.210 | M22L |
site-directed mutagenesis, the mutant shows slightly reduced activity with 4-nitrophenol compared to the wild-type enzyme |
-, 735475 |
| 1.14.13.210 | M22L/L380I |
error-prone PCR, protein engineering for nitrite removal, the mutant enzyme accepts two addtional substrates 4-nitrophenol and 3-methyl-4-nitrophenol. With 4-nitrophenol, the initial rate of the mutant M22L/L380I enzyme is 10fold higher than that of the wild-type enzyme, the catalytic efficiency for 4-nitrophenol degradation is 11fold higher, and with 3-methyl-4-nitrophenol, the initial rate is 4fold higher compared to the wild-type enzyme |
-, 735475 |
| 1.14.13.210 | M22L/L380M |
simultaneous saturation mutagenesis, the mutant shows slightly reduced activity with 4-nitrophenol compared to the wild-type enzyme |
-, 735475 |
| 1.14.13.210 | M22S/L380V |
simultaneous saturation mutagenesis, the mutant shows 20% enhanced degradation of 4-nitrophenol compared to mutant M22L/L380I |
-, 735475 |
