the enzyme is not sensitive to the prototypical catalase inhibitor 3-amino-1,2,4,-triazole in the presence of ascorbic acid (1.0 mM), metal chelating and sulfhydryl reagents do not significantly affect activity |
 |
| 1.11.1.19 | more |
not inhibited by EDTA, SDS, and NaCl |
|
| 1.11.1.19 | Mn2+ |
57.1% inhibition at 5 mM |
  |
| 1.11.1.19 | Mn2+ |
92.3% residual activity at 5 mM |
|
| 1.11.1.19 | Zn2+ |
88% residual activity at 5 mM |
|
| 1.11.1.19 | Ca2+ |
84.7% residual activity at 5 mM |
|
| 1.11.1.19 | H2O2 |
DyP activity for Reactive Blue 5 is inhibited when the H2O2 concentration exceeds 0.2 mM at a fixed DyP concentration of 0.6 nM. At 2.8 nM of DyP, its activity for 1,4-diamino-2-sodium anthraquinone sulfonate decreases sharply when the H2O2 concentration exceeds 0.1 mM |
|
| 1.11.1.19 | H2O2 |
DyP is inactivated by excess H2O2 |
|
| 1.11.1.19 | H2O2 |
maximum relative activity at final H2O2 concentrations between 0.4 and 0.8 mM, activity then gradually drops off. A residual activity of 30% still remains at 12.5 mM H2O2, and the enzyme is completely inactivated in the presence of 50 mM H2O2 |
