2.1.1.216 | 2 S-adenosyl-L-methionine + guanine26 in tRNA |
the efficient dimethylation of guanine26 requires the presence of base-pairs C11*G24 and G10*C25 and a variable loop of five bases within a correct 3D-core of the tRNA molecule. These identity elements probably ensure the correct presentation of methylated m2G26 to the enzyme for the attachment of the second methyl group |
