Abstract
Misacylated phenylalanyl-tRNALys, similar to lysyl-tRNALys, but not phenylalanyl-tRNAPhe, is able to serve as a substrate for ribosomal synthesis of polypeptides (poly-phenylalanine and polylysine, respectively) in the absence of a template polynucleotide (poly(A)). Thus, it is the structure of tRNA that determines the ability of the amino-acyl-tRNALys to participate in the peptide elongation on ribosomes without codon-anti-codon interactions.
