| - | '''Ribosome inactivating protein''' (RIP) is a bacterial or plant toxin which inhibits protein synthesis. RIP inactivates the ribosomal 60S subunit by N-glycosidic cleavage which results in releasing a specific adenine from 28S rRNA<ref>PMID:3510899</ref>. '''Type 1 RIP''' have a single chain, while '''type 2 RIP''' (i.e., ricin, ebulin and nigrin) have two chains. '''Momorcharin''' is a RIP isolated from several plants<ref>PMID:23777339</ref>. | + | '''Ribosome inactivating protein''' (RIP) is a bacterial or plant toxin which inhibits protein synthesis.
