Co2+ | displays remarkable activity in the absence of exogenous metals, although manganese, cobalt, and nickel all improve activity. Enzyme shifts its metal preference from Ni, Co,and Mn (decreasing order) when assayed at pH 6 to Ni, Mn, and Co (decreasing order) at pH 9 | Bacillus anthracis | |
Co2+ | enzyme is optimally active with cobalt at pH 6 | Helicobacter pylori | |
Mn2+ | displays remarkable activity in the absence of exogenous metals, although manganese, cobalt, and nickel all improve activity. Enzyme shifts its metal preference from Ni, Co,and Mn (decreasing order) when assayed at pH 6 to Ni, Mn, and Co (decreasing order) at pH 9 | Bacillus anthracis | |
additional information | Fe2+, Ca2+, Mg2+, Zn2+, Cu2+ have no effect on enzyme activity | Bacillus anthracis | |
Ni2+ | optimal arginase activity occurrs with nickel at an alkaline pH | Bacillus anthracis |
