TRNA:m4X modification enzyme
From Wikipedia, the free encyclopedia
TRNA:m4X modification enzyme (EC 2.1.1.225, TRM13, Trm13p, tRNA:Xm4 modification enzyme) is an enzyme with systematic name S-adenosyl-L-methionine:tRNAPro/His/Gly(GCC) (cytidine/adenosine4-2'-O)-methyltransferase.[1] This enzyme catalyses the following chemical reaction
- (1) S-adenosyl-L-methionine + cytidine4 in tRNAPro S-adenosyl-L-homocysteine + 2'-O-methylcytidine4 in tRNAPro
- (2) S-adenosyl-L-methionine + cytidine4 in tRNAGly(GCC) S-adenosyl-L-homocysteine + 2'-O-methylcytidine4 in tRNAGly(GCC)
- (3) S-adenosyl-L-methionine + adenosine4 in tRNAHis S-adenosyl-L-homocysteine + 2'-O-methyladenosine4 in tRNAHis
