Enzyme Information
| 3.2.2.22 |
rRNA N-glycosylase.
based on mapping to UniProt P10297
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.
