Publication Abstract from PubMed
Here we report the crystal structures of I.C and I.A wobble base pairs in the context of the ribosomal decoding center, clearly showing that the I.A base pair is of an I(anti).A(anti) conformation, as predicted by Crick. Additionally, the structures enable the observation of changes in the anticodon to allow purine-purine base pairing, the 'widest' base pair geometry allowed in the wobble position.
