FunFam 1886: tRNA (guanine-N(1)-)-methyltransferase

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
TRNA (guanine(37)-N(1))-methyltransferase. [EC: 2.1.1.228]
S-adenosyl-L-methionine + guanine(37) in tRNA = S-adenosyl-L-homocysteine + N(1)-methylguanine(37) in tRNA.
  • This enzyme is important for the maintenance of the correct reading frame during translation.
  • Unlike TrmD from Escherichia coli, which recognizes the G(36)pG(37) motif preferentially, the human enzyme (encoded by TRMT5) also methylates inosine at position 37.
  • Formerly EC 2.1.1.31.
