Crystal structure of tRNA (Um34/Cm34) methyltransferase TrmL from Escherichia coli with SAH

Template:ABSTRACT PUBMED 23804755

Function

[TRML_ECOLI] 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. Recognition of the target requires a pyridine at position 34 and N(6)-(isopentenyl)-2-methylthioadenosine at position 37.[1]

About this Structure

4jal is a 2 chain structure with sequence from Ecoli. Full crystallographic information is available from OCA.
