In bacteria and organelles, the initiation of protein synthesis is signaled by the formation of formyl-methionyl-tRNA (tRNAfMet). fMet is only used for the initiation of protein synthesis and is thus found only at the N terminus of the protein. Once protein synthesis is accomplished, the formyl group on methionine can be removed by peptide deformylase. Lit.
