FunFam 142: Ribosome-inactivating protein momordin I

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
RRNA N-glycosylase. [EC: 3.2.2.22]
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.
