5CD1, 5CCB, 5CCX - PubMed Abstract: 
Human tRNA3(Lys) is the primer for reverse transcription of HIV; the 3' end is complementary to the primer-binding site on HIV RNA. The complementarity ends at the 18th base, A58, which in tRNA3(Lys) is modified to remove Watson-Crick pairing. Motivated to test the role of the modification in terminating the primer-binding sequence and thus limiting run-on transcription, we asked how the modification of RNA could be accomplished ...
