The Biological Elongation Process: Building Proteins

Within the cell, peptide elongation is an essential part of protein synthesis. It follows the initiation phase, where a ribosome assembles on an mRNA molecule. During elongation, the ribosome moves along the mRNA sequence, reading amino acid composition of the peptide being synthesized and adding corresponding amino acids to a growing polypeptide chain. This process is facilitated by elongation factors, which are protein factors uniquely required during this phase.Peptide chain elongation rate.

A key player in this process is Peptide Elongation Factor Tu (EF-Tu), a protein found in bacteria and eukaryotic mitochondria. EF-Tu delivers aminoacyl-tRNAs (tRNAs carrying specific amino acids) to the ribosome's A site. The A site is where incoming tRNAs bind, while the P site holds the tRNA attached to the growing polypeptide chain. The elongation is when the polypeptide chain gets longer as a new amino acid is added. This cyclic process involves several steps: aminoacyl-tRNA binding, peptidyl transfer (forming a new peptide bond), and translocation (moving the ribosome along the mRNA).
