1) endo-exonuclease
核酸内外切酶
1.
On shifting rapidly growing mycelia culture of Neurospora crassa from 30℃ to 45℃ for 2h,75% of active endo-exonuclease, an enzyme implicated previously in DNA repair, was released from both nuclei and vacuoles into the cytosol where it was inactivated.
将快速生长的粗糙脉孢菌Ｎｅｕｒｏｓｐｏｒａｃｒａｓｓａ培养液从３０℃升温至４５℃，热休克处理２小时，７５％有活性的核酸内外切酶ｅｎｄｏ－ｅｘｏｎｕｌｅａｓｅ（此酶为ＤＮＡ修复酶）从核及液泡中释放到胞质并以无活性的形式储存起来：用放线菌酮处理，不能阻止此酶的释放，但能使灭活降低；致使胞质的酶活性提高５－１５倍。

5) endoribonuclease
核糖核酸内切酶
6) endoribonuclease
内切核糖核酸酶
补充资料：核酸外切酶
核酸外切酶
能将多核苷酸水解以产生单核苷酸的酶(磷酸二酯类）降解作用，从链的一端陆续向另一端进行。可从c-5′端向c-3端(5′→3′核酸外切酶），也可沿相反方向(3′→5′核酸外切酶）进行。
