3.4.11.15 | Co2+ |
0.2 mM, 4fold stimulation. When the sample is preincubated with 0.2 mM Co2+ ions and subjected to gel filtration, only 10% of the activity remains, while addition of Co2+ (0.2 mM) to the reaction mixture completely restores enzyme activity. Co2+ions could not be replaced with other divalent (Ca2+, Cd2+, Cu2+, Fe2+, Mg2+, Mn2+, Ni2+, or Zn2+) or monovalent cations (Na+or K+) when used at concentrations of up to 0.2 mM |
