AbstractDirect interaction of Cu2Zn2SOD with inorganic metal compound(CoCl2) and organic metal compound [Co(II) (His)(n)] was studied by ICP,VIS,NMR and measurement of enzyme activity. It has been found that in aqueous solution,there exists a direct interaction of the metal ions of the active center in the metalloenzyme (Cu(2)Zn(2)ZSOD)with external added CoCl2,Co (His)(n). As a result,part of the metal ions in metalloenzyme were replaced and the corresponding metalloenzyme derivatives were produced and the catalytic activity of enzyme were affected. Moreover. The interaction of Co(II)(His)(n) with Cu2Zn2SOD is stronger and quicker,than that of CoCl2 with this enzyme, as well as th Co( I) from Co(H >(His)(n) is easier to enter the active center of enzyme.
