The activity of the enzyme was strongly inhibited by Cu2+,Fe2+,Fe3+,Zn2+and EDTA,while Na+,Li+ had no effect on it. Mn2+,Mg2+ had a little inhibition and K+,Ca2+ had a little activation on its activity.
|
|
|
金属离子Cu2+、Fe2+、Fe3+、Zn2+及金属鏊合剂EDTA和柠檬酸盐离子对酶活有显著抑制作用,Mn2+、Mg2+有微弱的抑制作用,K+、Ca2+和表面活性剂SDS有微弱的激活作用,而其他一些离子如Na+、Li+则对酶活影响不大. |
