WebType I ribosome-inactivating proteins (RIPs) are plant toxins that inhibit protein synthesis by exerting rRNA N-glycosylase activity (EC 3.2.2.22). Due to the lack of a cell-binding domain, type I RIPs are not target cell-specific. However once linked to antibodies, so called immunotoxins, they are promising candidates for targeted anti-cancer therapy. In this … WebA ribosome is a cellular structure not bounded by a membrane, composed of ribosomal RNA and proteins, and whose function is to synthesize proteins. The ribosome’s function in protein synthesis is so critical for all cellular activities that two Nobel prizes have been awarded to research teams that study the ribosome.
