| 摘 要： | 小麦ＳＯＤ有４条同功酶谱带，迁移率最慢的为Ｍｎ－ＳＯＤ，其余三种同功酶是Ｃｕ、Ｚｎ－ＳＯＤ。小麦ＳＯＤⅢ的分子量为３０４００ｄａｌｔｏｎ其氨基酸组成中甘氨酸含量最大，不含甲硫氨酸；在较宽的温度范围内有酶活性，在偏碱性环境中酶活性较高，但ｐＨ＞１３后活性迅速下降。

| Abstract: | There were four different SOD isozymes in wheat seedling. The mobility ofMnSOD was the slowest in electrophoresis.The other three isozymes were Cu、Zn-SOD.The SOD Ⅲ was purified. Its molecular weight was 30400 daltons.In itscomposition Gly content wns the highest and no Cys existed.The SOD Ⅲ had higheractivity within a wide temperature and in alkalescent condition.IF PH> 13,the activi-ty decreased singificantly. |
