[Ribosome + protein elongation factors of the ribosomal cycle as a single enzyme. Why are protein factors needed?].
Model of ribosomal cycle with participation of protein elongation factors is discussed. According to this model both elongation factors should help to ribosome to discriminate substrates versus products of reactions. For aminoacyl site it is a discrimination of aa-tRNA versus tRNA, and for peptidyl site-discrimination of peptidyl-tRNA versus tRNA.
