| 摘 要： | 本文测定了猪肺炎霉形体膜上ＡＴＰ酶的活性，同时就温度、ｐＨ及一些金属离子对该ＡＴＰ酶活性的影响进行了研究。结果表明：猪肺炎霉形体膜上ＡＴＰ酶比活力为９．２３２左右。在２５～４０℃温度范围内酶活性较稳定。ｐＨ适应范围为６．５～８之间，以ｐＨ７．６为最适。Ｍｇ２＋、Ｍｎ２＋、Ｚｎ２＋对酶均有一定程度的激活作用，而Ｃａ２＋、Ｎａ＋－Ｋ＋具有不同程度的抑制作用。

| Abstract: | The membrane-bound atpase activity of mycoplasma hyopneumoniae were tested and the effect of temperature,PH and some metal-ions on the ATPase activity were studied.The results show:the ATPase specific activity on mycoplasma hyopneumoniae is about 9. 232,Enzyme activity is stable comparativily on the condition of 25 C￣40 C.PH range from 6.5 to 8,and the fittest value is 7.6.Mg2+,Mn2+and Zn2+all have certain stimulus function.Whereras Ca2+,Na+-K+have the different extent inhibitory effect. |
