Theoretical and experimental approach to recognition of amino acid by tRNA.

The C4N model concludes that the pocket on the complex of the anticodon bases and the discriminator base on a tRNA can accept the corresponding protein amino acid. A theoretical molecular computation by using the energy minimum principle is carried out to find the energy-refined C4N conformation. The results for Gln and Val suggest that not only the lock and key relationship but the induced fitting effect occurs. Some experiments to detect the interaction between the polynucleotides and the amino acid are being attempted.
