Protein

tRNA (guanine-N(7)-)-methyltransferase

Gene

TRM8

Organism
Saccharomyces cerevisiae (strain YJM789) (Baker's yeast)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Methyltransferase that catalyzes the formation of N(7)-methylguanine at position 46 (m7G46) in tRNA, a modification required to maintain stability of tRNAs; its absence resulting in tRNA decay. Both the D-stem and T-stem structures of tRNAs are required for efficient methyltransferase activity.UniRule annotation

Catalytic activityi

S-adenosyl-L-methionine + guanine(46) in tRNA = S-adenosyl-L-homocysteine + N(7)-methylguanine(46) in tRNA.UniRule annotation
