Abstract
In this paper the effects of five kinds of divalent metal ions on LDH activity were studied. The results showed that Zn2+ and Ca2+ do not af fect LDH activity while Mn2+ exerted inhibitory effect. At low concent rations, Cu2+ and Mg2+ slightly stimulate LDH activity, From the bindi ng model of ternary complex, it could be concluded that I,DH is a non- metallic enzyme and Zn2+. did not play a catalytic role in LDH. The di fferent effects of CU2+, Mg2+, Mn2+ and Ca2+ ions were also discussed.
