- Protein existenceInferred from homology
- Annotation score3/5
Function
function
Specifically methylates the N1 position of guanosine-37 in various cytoplasmic and mitochondrial tRNAs. Methylation is not dependent on the nature of the nucleoside 5' of the target nucleoside. This is the first step in the biosynthesis of wybutosine (yW), a modified base adjacent to the anticodon of tRNAs and required for accurate decoding.
Catalytic activity
- guanosine37 in tRNA + S-adenosyl-L-methionine = H+ + N1-methylguanosine37 in tRNA + S-adenosyl-L-homocysteine
