FunFam 87378: ATP-binding domain-containing protein 4

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
Diphthine--ammonia ligase. [EC: 6.3.1.14]
ATP + diphthine-[translation elongation factor 2] + NH(3) = AMP + diphosphate + diphthamide-[translation elongation factor 2].
  • This amidase catalyzes the last step in the conversion of an L-histidine residue in the translation elongation factor translation elongation factor 2 to diphthamide.
  • This factor is found in all archaebacteria and eukaryotes, but not in eubacteria, and is the target of bacterial toxins such as the diphtheria toxin and the Pseudomonas exotoxin A (see EC 2.4.2.36).
  • The substrate of the enzyme, diphthine, is produced by EC 2.1.1.98.
  • Formerly EC 6.3.2.22.
