LITERATURE
Co3+
strictly metal-dependent nuclease. It exhibits activity in the presence of Mg2+, Mn2+, Co2+ or Ni2+, whereas no activity is observed in the absence of these metal ions. Little activity is detected in the presence of other metals including Co3+, Cu2+, Zn2+, and Ca2+
Cu2+
strictly metal-dependent nuclease. It exhibits activity in the presence of Mg2+, Mn2+, Co2+ or Ni2+, whereas no activity is observed in the absence of these metal ions. Little activity is detected in the presence of other metals including Co3+, Cu2+, Zn2+, and Ca2+
Na+
the enzyme exhibits the highest activity in the presence of 100 mm NaCl
NH4Cl
-
enzyme form H2 is mostly inactive at low salt and requires 100-200 mM concentration for maximal activity. NH4Cl is more efficient than NaCl
