TRNA (uracil-5-)-methyltransferase : ウィキペディア英語版 | TRNA (uracil-5-)-methyltransferase
In enzymology, a tRNA (uracil-5-)-methyltransferase () is an enzyme that catalyzes the chemical reaction :S-adenosyl-L-methionine + tRNA containing uridine at position 54 S-adenosyl-L-homocysteine + tRNA containing ribothymidine at position 54 Thus, the two substrates of this enzyme are S-adenosyl methionine and tRNA containing uridine at position 54, whereas its two products are S-adenosylhomocysteine and tRNA containing ribothymidine at position 54. This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:tRNA (uracil-5-)-methyltransferase. Other names in common use include ribothymidyl synthase, transfer RNA uracil 5-methyltransferase, transfer RNA uracil methylase, tRNA uracil 5-methyltransferase, m5U-methyltransferase, tRNA:m5U54-methyltransferase, and RUMT. ==References==
