Co2+
CoCl2
metal ion removal from the purified Sumo-ArgE decreases enzyme activity by nearly 90% in reactions without added CoCl2 in comparison with those containing 0.2 mM CoCl2
MnCl2
metal ion removal from the purified Sumo-ArgE decreases enzyme activity by nearly 90% in reactions without added CoCl2 in comparison with those containing 0.2 mM CoCl2. MnCl2 (0.2 mM) added to the reaction in place of CoCl2 restores activity to about 40 % of that seen with CoCl2
Zn2+
additional information
-
90% of full activity upon addition of one metal ion
Zn2+
-
0.1 mM activity increases 2-fold, further increase in concentration results in inhibition
Zn2+
-
required, the enzyme binds two Zn(II) ions in non-interactive binding sites with Kd values for the first Zn(II) binding event of 0.0027 mM, whereas the observed Kd values for the second metal binding event in DapE is 0.051 mM
