Comments [?]

case <OC:Proteobacteria>
Function Methylates the ribose at the nucleotide 34 wobble position in the two leucyl isoacceptors tRNA(Leu)(CmAA) and tRNA(Leu)(cmnm5UmAA). Catalyzes the methyl transfer from S-adenosyl-L-methionine to the 2'-OH of the wobble nucleotide.
else
Function Could methylate the ribose at the nucleotide 34 wobble position in tRNA.
end case
Catalytic activity RHEA:43084: cytidine(34) in tRNA + S-adenosyl-L-methionine = 2'-O-methylcytidine(34) in tRNA + H(+) + S-adenosyl-L-homocysteine
EC 2.1.1.207
RHEA:43088: 5-carboxymethylaminomethyluridine(34) in tRNA(Leu) + S-adenosyl-L-methionine = 5-carboxymethylaminomethyl-2'-O-methyluridine(34) in tRNA(Leu) + H(+) + S-adenosyl-L-homocysteine
EC 2.1.1.207
case <OC:Proteobacteria>
Subunit Homodimer.
end case
Subcellular location Cytoplasm.
Similarity Belongs to the class IV-like SAM-binding methyltransferase superfamily. RNA methyltransferase TrmH family. TrmL subfamily.
