fMet is a starting residue in the synthesis of proteins in bacteria, and, consequently, is located at the N-terminus of the growing polypeptide. fMet is delivered to the ribosome (30S) - mRNA complex by a specialized tRNA (tRNA ) which has a 3'-UAC-5' anticodon that is capable of binding with the 5'-AUG-3' start codon located on the mRNA. fMet is thus coded by the same codon as methionine; however, AUG is also the translation initiation codon. When the codon is used for initiation, fMet i… Web1. The use of a Met-accepting tRNA with an anticodon that recognises AUG to insert the first amino acid in a protein. 2.
