In bacteria. all nascent proteins bear the pretranslationally formed N-terminal formyl-methionine (fMet) residue. The fMet residue is cotranslationally deformylated by a ribosome-associated deformylase. The formylation of N-terminal Met in bacterial proteins is not strictly essential for either translation or cell viability. https://www.sukrensi.com/flash-offer-ILOOTPAPERIE-Washi-Tape-best-find/
