FunFam 5594: Mrna capping enzyme alpha

There are 2 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
MRNA guanylyltransferase. [EC: 2.7.7.50]
GTP + (5')pp-Pur-mRNA = diphosphate + G(5')ppp-Pur-mRNA.
  • Can modify also synthetic poly(A) and poly(G) to form the structures m(7)G(5')pppAn and m(7)G(5')pppGn.

Polynucleotide 5'-phosphatase. [EC: 3.1.3.33]
A 5'-phosphopolynucleotide + H(2)O = a polynucleotide + phosphate.
  • Does not act on nucleoside monophosphates.
  • Induced in Escherichia coli by T-even phages.
