-==Overview==
+==TRNA POSITIONS DURING THE ELONGATION CYCLE==
-Three-dimensional cryomaps have been reconstructed for tRNA-ribosome, complexes in pre- and posttranslocational states at 17-A resolution. The, positions of tRNAs in the A and P sites in the pretranslocational, complexes and in the P and E sites in the posttranslocational complexes, have been determined. Of these, the P-site tRNA position is the same as, seen earlier in the initiation-like fMet-tRNA(f)(Met)-ribosome complex, where it was visualized with high accuracy. Now, the positions of the A-, and E-site tRNAs are determined with similar accuracy. The positions of, the CCA end of the tRNAs at the A site are different before and after, peptide bond formation. The relative positions of anticodons of P- and, E-site tRNAs in the posttranslocational state are such that a, codon-anticodon interaction at the E site appears feasible.
