2.1.1.206 |
Accepted name: |
tRNA (cytidine56-2′-O)-methyltransferase |
Reaction: |
S-adenosyl-L-methionine + cytidine56 in tRNA = S-adenosyl-L-homocysteine + 2′-O-methylcytidine56 in tRNA |
Other name(s): |
aTrm56; tRNA ribose 2′-O-methyltransferase aTrm56; PAB1040 (gene name) |
Systematic name: |
S-adenosyl-L-methionine:tRNA (cytidine56-2′-O)-methyltransferase |
Comments: |
The archaeal enzyme specifically catalyses the S-adenosyl-L-methionine dependent 2′-O-ribose methylation of cytidine at position 56 in tRNA transcripts. |
