The requirement of ATP and extra-ribosomal proteins for the inactivation of ribosomes by eight plant RNA N-glycosidases [ribosome-inactivating proteins (RIPs)] was investigated. Tritin, pokeweed antiviral protein and barley RIP depend, as gelonin [Sperti, S., Brigotti, M., Zamboni, M., Carnicelli, D. and Montanaro, L. (1991) Biochem. J., 277, 281-284], on the presence of ATP and extra-ribosomal proteins for full inactivation of ribosomes, while bryodin, lychnin, momordin, momorcochin and saporin inactivate isolated Artemia salina ribosomes suspended in buffer saline.
研究了8种植物RNA N-糖苷酶[核糖体失活蛋白（RIPs）]使核糖体失活对ATP和核糖体外蛋白质的需求。与gelonin [Sperti, S., Brigotti, M., Zamboni, M., Carnicelli, D.和Montanaro, L. (1991) Biochem. J., 277, 281 - 284]一样，天花粉蛋白、商陆抗病毒蛋白和大麦RIP使核糖体完全失活依赖于ATP和核糖体外蛋白质的存在，而苔藓抑素、剪秋罗素、苦瓜素、苦瓜凝集素和皂草素能使悬浮于缓冲盐溶液中的卤虫核糖体失活。
