摘要:
噬菌体裂解酶因高效、安全的杀菌特性成为潜在的抗菌药物,并受到广泛关注。本试验在前期通过基因表达制备高效噬菌体裂解酶Lys BT1的基础上,深度解析Lys BT1与细菌上裂解酶受体相互作用的结构特点,成功构建出质粒pCAMBIA 1301-BT1。将该质粒通过电转化的方式导入普通小球藻中,电转条件为：电场强度1.5 kV、脉冲距离2 mm、脉冲时间0.2 ms,瞬时表达后成功进行了活性测定，从而验证了普通小球藻作为裂解酶表达载体的可行性,为噬菌体裂解酶的表达系统研发提供了一条可行路径。
Abstract:
Bacteriophage lyase has become a potential antibacterial drug due to its high efficiency and safe bactericidal properties, and has been widely concerned. In this study, based on the preparation of high-efficiency bacteriophage lyase Lys BT1 by gene expression in the early stage, we deeply analyzed the structural characteristics of Lys BT1 interacting with the lyase receptor on bacteria, and successfully constructed the plasmid pCAMBIA 1301-BT1. The plasmid was introduced into Chlorella vulgaris by electrotransformation. The electrotransformation conditions were as follows: electric field intensity of 1.5 kV, pulse distance of 2 mm, and pulse time of 0.2 ms. After transient expression, the activity determination was successfully carried out. Therefore, the feasibility of Chlorella vulgaris as a lyase expression vector was verified, which provided a feasible path for the development of bacteriophage lyase expression system.
