rRNA N-glycosylase (EC 3.2.2.22, ribosomal ribonucleate N-glycosidase, nigrin b, RNA N-glycosidase, rRNA N-glycosidase, ricin, momorcochin-S, Mirabilis antiviral protein, gelonin, saporins) is an enzyme with systematic name rRNA N-glycohydrolase.[1] This enzyme catalyses the following chemical reaction
- Hydrolysis of the N-glycosylic bond at A-4324 in 28S rRNA from eukaryotic ribosomes.
Ricin A-chain and related toxins show this activity.
