Abstract

Several amino acid analogues that are able to replace amino acid residues in binding positions of the biologically active C-terminal tetrapeptide amide sequence, Trp-Met-Asp-PheNH2, of the gastrins were examined for their ability to inhibit the aminoacylation of tRNA in an Escherichia coli and rat liver system. Although in both systems the amino acid side chains are involved in the recognition process, the structural requirements of the side chain in the two systems are not comparable. Analogues of methionine and phenylalanine behaved similarly in the E. coli and rat liver systems, whereas analogues of tryptophan behaved differently. From the results it is possible to suggest structural features of the amino acid side chains which are required for recognition by the aminoacyl-tRNA synthetases.
