|
| Reactions |
(1) S-adenosyl-L-methionine + cytidine(4) in tRNA(Pro) = S-adenosyl-L- homocysteine + 2′-O-methylcytidine(4) in tRNA(Pro). (2) S-adenosyl-L-methionine + cytidine(4) in tRNA(Gly)(GCC) = S-adenosyl- L-homocysteine + 2′-O-methylcytidine(4) in tRNA(Gly)(GCC). (3) S-adenosyl-L-methionine + adenosine(4) in tRNA(His) = S-adenosyl-L- homocysteine + 2′-O-methyladenosine(4) in tRNA(His). |
