Summary of biochemical properties of the three canonical Dps proteins in N. punctiforme
| Protein | DNA-binding capacity | Ferroxidase activity under consumption of H2O2a | Condition for dodecamer stability |
|---|---|---|---|
| NpDps1 | No | Yes | pH 6.0 |
| NpDps2 | Yesb | Yes | pH 6.0 |
| NpDps3 | Yesb | Yes | pH 6.0, pH 8.0 |
a Fe2+ oxidation under the consumption of O2 was not observed.
b Putative DNA-binding motif at the N or C terminus identified (see Fig. S1).
