1EUQ, 1EUY - PubMed Abstract: 
The position of the tertiary Levitt pair between nucleotides 15 and 48 in the transfer RNA core region suggests a key role in stabilizing the joining of the two helical domains, and in maintaining the relative orientations of the D and variable loops. E. coli tRNA(Gln) possesses the canonical Pu15-Py48 trans pairing at this position (G15-C48), while the tRNA(Cys) species from this organism instead features an unusual G15-G48 pair ...
