An engineered “amber 1986-01-01 This carries formylmethionine (prokaryotes) and initiation methionine (eukaryotes) to the P site of the ribosome to begin translation. The structure of this tRNA can be distinguished from the rest of the transfer RNAs. This rRNA in bacteria, besides the AUG, may recognize GUG and UUG as a formylmethionine codon. The initiator tRNAplays an important role in this process and in the selectionof the appropriate initiation codon. Because of its specialfunction, an initiator tRNA possesses many highly specific properties that are different from those of elongatortRNAs (RajBhandary 1994).

IF2 was immobilized on the surface of a CM5 chip and the Formylation is not strictly necessary, because nonformylated Met-tRNA f can function as an initiator, but it improves the efficiency with which the Met-tRNA f is used, because it is one of the features recognized by the factor IF-2 that binds the initiator tRNA (Sundari et al., 1976).; The bases that face one another at the last position of the stem to which the amino acid is connected are The name of the aminoacyl-tRNA is usually abbreviated to fMet-tRNA f.

any of a class of small, cloverleaf forms of RNA that transfer unattached amino acids in the cell cytoplasm to the ribosomes for protein synthesis. Initiator tRNA Met (also known as tRNA fmet) is a tRNA used by some organisms for translation initiation.
