Co2+
most potent activator, Km: 0.0002 mM, binds 2 mol Co2+ per mol of racemase
Mn2+
increases activity to a smaller extent than Co2+
more
enzyme does not require tightly bound metal ions for activity, they are not released even after extensive dialysis at pH 2.4
Ni2+
increases activity to a smaller extent than Co2+
Zn2+
increases activity to a smaller extent than Co2+
Co2+
increases activity
Co3+
lower level of activation than Co2+ at higher concentrations
Fe2+
lower level of activation than Co2+ at higher concentrations
Mn2+
lower level of activation than Co2+ at higher concentrations
more
His12, Gln65, His91 and Glu141 provide a binding site for a divalent metal ion, as shown by binding of Co2+
