the enzyme uses more efficiently Phe-tRNAPhe than any of the Leu-tRNALeu. The efficiency of cyclo(L-phenylalanyl-L-phenylalanyl) synthesis is not affected by the presence of Leu-tRNALeuGAG or Leu-tRNALeuTAA indicating that these molecules do not compete with Phe-tRNAPhe for binding to the enzyme. In contrast, Leu-tRNALeuCAA, Leu-tRNALeuTAG or or Leu-tRNALeuCAG isoacceptors inhibit cyclo(L-phenylalanyl-L-phenylalanyl) synthesis revealing a competition with Phe-tRNAPhe
