植物核糖体失活蛋白 (ribosome inactivatingprotein ,RIP)通常按分子结构不同分为两型 :Ⅰ型RIP为单链蛋白 ,如天花粉蛋白 ;Ⅱ型RIP是通过二硫键连接的双链蛋白 ,如蓖麻毒素。Ⅰ型RIP与Ⅱ型RIP的A链一样 ,是一类RNAN 糖苷酶或多核苷酸∶腺苷糖苷酶 ,具有抗生育、抗病毒和抗肿
Plant ribosome inactivating protein (RIP) is usually divided into two types according to the molecular structure: type I RIP is a single chain protein such as trichosanthin; type II RIP is a double-stranded protein linked by a disulfide bond, Hematin. Type I RIP, like the type A RIP of type II, is a class of RNAN glycosidases or polynucleotides: adenosylglycosidase with anti-fertility, antiviral and anti-swollen
