Plant ribosome-inactivating proteins (RIPs) are N-glycosidases which inhibit protein synthesis through depurination of the ribosomal RNA sequence. Type II RIPs are heterodimer proteins which can bind to cell surfaces. The cytotoxicity of these RIPs is different. spp. are a rich source of RIP proteins with different properties. In the present study, a type II RIP was isolated from plant that grows widely in the north of Iran, and different bioinformatics tools were used for the evaluation of physicochemical, functional and 3D protein characteristics. The results showed significant differences among isolated RIP and other Sambucus RIP proteins. The study of these differences can not only expand our insight into the functioning mechanisms of plant RIPs but also provide information about a novel RIP protein with potential biological applications.
植物核糖体失活蛋白(RIPs)是一种N-糖苷酶,可通过使核糖体RNA序列脱嘌呤来抑制蛋白质合成。II型RIPs是能够结合细胞表面的异源二聚体蛋白。这些RIPs的细胞毒性各不相同。接骨木属植物是具有不同特性的RIP蛋白的丰富来源。在本研究中,从广泛生长于伊朗北部的接骨木属植物中分离出一种II型RIP,并使用不同的生物信息学工具评估其理化、功能和三维蛋白质特征。结果表明,分离出的RIP与其他接骨木属RIP蛋白之间存在显著差异。对这些差异的研究不仅可以扩展我们对植物RIPs作用机制的认识,还可以提供有关具有潜在生物学应用的新型RIP蛋白的信息。
