    5.1.99.1 | Co2+ |
most potent activator, Km: 0.0002 mM, binds 2 mol Co2+ per mol of racemase |
2434 |
| 5.1.99.1 | Mn2+ |
increases activity to a smaller extent than Co2+ |
2437 |
| 5.1.99.1 | more |
enzyme does not require tightly bound metal ions for activity, they are not released even after extensive dialysis at pH 2.4 |
