Enzyme Information
| 2.1.1.297 |
Peptide chain release factor N(5)-glutamine methyltransferase.
based on mapping to UniProt P0ACC1
S-adenosyl-L-methionine + [peptide chain release factor 1 or 2]-L- glutamine = S-adenosyl-L-homocysteine + [peptide chain release factor 1 or 2]-N(5)-methyl-L-glutamine.
-!- Modifies the glutamine residue in the universally conserved glycylglycylglutamine (GGQ) motif of peptide chain release factor, resulting in almost complete loss of release activity. -!- Formerly EC 2.1.1.n16.
