摘要
在粘虫痘病毒包涵体中检测到一种碱性蛋白酶。最适ｐＨ为８．８，最适温度为２０℃，是热不稳定的，可被２－硫基乙醇激活，其活性不需二价阳离子。在粘虫痘病毒颗粒中检测到两种脱氧核糖核酸酶，均能降解变性的大肠杆菌ＤＮＡ，最适ｐＨ分别为５．０和８．
An alkaline protease has been detected within the inclusion body of Leucania Separata Entomopoxvirus(LsEPV). The protease has an optimum pH of 8.8 and an optimum temperature of 20℃, it is heat labile, and can be activated by 2-mercaptoethanol Two DNase,both hydrolizing single-strand E. coli DNA with optimum pH of 5.0 and 8.0 separately, were identified within highly purified virus particles of LsEPV.
