文摘内容 The effects of five metal ions(Fe-'~,Ca-~*,Mg2*,Mn-'-Cu2) on ABTS oxidation catalyzed by laccase werestudied under condition of pH=4.5 byspectrophotometer. The results show that Fe2+ ionhas obvious effect on the activity and the nature ofinhibition is competitive type. It is found that theinhibition is realized through the reduction ofABTS.by Fe2+ ion. Other metal ions have slight influence onlaccase activity。
