FunFam 1: m7GpppX diphosphatase

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
5'-(N(7)-methyl 5'-triphosphoguanosine)-[mRNA] diphosphatase. [EC: 3.6.1.59]
A 5'-(N(7)-methyl 5'-triphosphoguanosine)-[mRNA] + H(2)O = N(7)- methylguanosine 5'-phosphate + a 5'-diphospho-[mRNA].
  • The enzyme removes (decaps) the N(7)-methylguanosine 5-phosphate cap from an mRNA degraded to a maximal length of 10 nucleotides.
  • Decapping is an important process in the control of eukaryotic mRNA degradation.
  • The enzyme functions to clear the cell of cap structure following decay of the RNA body.
  • The nematode enzyme can also decap triply methylated substrates, 5'-(N(2),N(2),N(7)-trimethyl 5'-triphosphoguanosine)-[mRNA].
  • Formerly EC 3.6.1.30.
