Bacterial Protein Synthesis

Bacterial protein synthesis is the essential process by which bacteria create proteins necessary for their survival, growth, and function. It occurs in the cytoplasm using 70S ribosomes (30S and 50S subunits) and involves the translation of mRNA into polypeptide chains. This process is a major target for antibiotics due to key differences between bacterial and eukaryotic ribosomes, allowing for selective inhibition of bacterial growth. The steps include initiation (assembly of ribosomal subunits and initiator tRNA), elongation (sequential addition of amino acids based on mRNA codons), termination (release of the polypeptide chain), and ribosome recycling. A unique feature is the use of N-formylmethionine (fMet) as the initiator tRNA. Antibiotics targeting this pathway include aminoglycosides, tetracyclines, macrolides, chloramphenicol, and linezolid.
