TRM7

Gene
TRM7
Protein
tRNA (cytidine(32)/guanosine(34)-2'-O)-methyltransferase
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Length
310 amino acids
Function
Methylates the 2'-O-ribose of nucleotides at positions 32 and 34 of the tRNA anticodon loop of tRNA(Phe), tRNA(Trp) and tRNA(Leu(UAA)). Requires TRM732 for methylation of the cytidine at position 32 and RTT10/TRM734 for methylation of the nucleotides at position 34 in substrate tRNAs. Lack of either of these modifications in tRNA(Phe) reduces formation of wybutosine from 1-methylguanosine at position 37.
Similarity
Belongs to the class I-like SAM-binding methyltransferase superfamily. RNA methyltransferase RlmE family. TRM7 subfamily.
