2'-O-methyl-1-methyl adenosine: a new modified nucleoside in ragi (Eleusine coracana) tRNA

A new modified nucleoside 2'-O-methyl-l-methyl adenosine has been found to be present in the tRNA of Eleusine coracana ( ragi ) seedlings. The sequence of the dinucleotide of which this modified nucleoside is a part suggests its presence in phenylalanine-tRNA. The structural implications of the presence of this new modification are discussed.
