Isoleucyl initiator tRNA does not initiate eucaryotic protein synthesis.

Initiator tRNA from yeast (tRNAMeti) was quantitatively misaminoacylated with L-isoleucine using isoleucyl-tRNA synthetase from Escherichia coli. Surprisingly the misaminoacylated Ile-tRNAMeti neither participates in nor inhibits the initiation of globin synthesis in a rabbit reticulocyte lysate, whereas Met-tRNAMeti readily initiates protein synthesis in the same system. The incompetent behavior of Ile-tRNAMeti may be related to the observation that in vitro it does not form a stable complex with eucaryotic initiation factor 2 (eIF-2) and GTP, under conditions which lead to a stable eIF-2 X GTP X Met-tRNAMeti ternary complex. This indicates that eIF-2 can discriminate between the side chains of the aminoacyl adducts of the tRNAMeti during ternary complex formation, the first essential step in initiation of eucaryotic protein synthesis.[1]
