    1.4.1.4 | C141S |
reductive amination activity of C141S alone is insensitive to treatment with 2-hydroxyethyl disulfide |
743643 |
| 1.4.1.4 | C321A |
site-directed mutagenesis, the mutant shows reduced NADP-related GDH activity, the mutation causes a greater than a 2fold drop in Vmax and more than a 2fold increase in Km for NADP+ |
762699 |
| 1.4.1.4 | C415S |
mutant loses its reductive amination activity in a manner very similar to the native enzyme |
743643 |
| 1.4.1.4 | D167T |
the mutant enzyme is slightly more thermostable than the wild-type enzyme |
-, 728754 |
