a The nuclease activity of purified SsnA was quantified at pH ranging from 4.5 to 11. b Using the quantitative fluorescent assay, the DNase activity of SsnA was tested in the presence of a range of Mn2+, Ca2+, Mg2+ and Zn2+ concentrations. Negative controls without enzyme are indicated. In all panels, points or bars indicate means from 3 independent experiments and SE is shown.
