Enzyme Information
| 3.2.2.22 | 
							 rRNA N-glycosylase. 
							based on mapping to UniProt P09989 		
							Endohydrolysis of the N-glycosidic bond at one specific adenosine on the 28S rRNA. 
							-!- Ricin A-chain and related toxins show this activity. -!- Naked rRNA is attacked more slowly than rRNA in intact ribosomes. -!- Naked rRNA from Escherichia coli is cleaved at a corresponding position.
