Multiple stages in codon-anticodon recognition: double-trigger mechanisms and geometric constraints.

Abstract excerpt

Thirty years of kinetic studies on tRNA selection in the elongation cycle are reviewed, and confronted with results derived from various sources, including structural studies on the ribosome, genetic observations on ribosome and EF-Tu accuracy mutants, and codon-specific elongation rates. A coherent framework is proposed, which gives meaning to many puzzling effects. Ribosomal accuracy would be governed by a...
