395489 |
| 1.13.11.52 | freezing and thawing causes 66% loss of activity |
395493 |
| 1.13.11.52 | guanidine hydrochloride, 30°C, 30 min, about 15% loss of activity at 0.5 M, about 30% loss of activity at 1 mM, about 60% loss of activity at 2 M, complete loss of activity at 3 mM |
395455 |
| 1.13.11.52 | the enzyme is unstable in the presence of reductants and oxygen and heme-binding ligands increase its stability |
765221 |
| 1.13.11.52 | unstable in purified state, if the substrate is omitted during the last step, the activity is lost entirely |
