Protein Synthesis | NOVA Labs | PBS

Directed by genes, living organisms synthesize polypeptides using amino acids. The unique order of amino acids in a polypeptide is called the and represents the first level of a protein’s three-dimensional structure (conformation). The primary structure determines every additional level of chemical interactions, directing the formation of a protein’s final conformation.

DNA Replication, and 3. Protein Synthesis, all involving manipulation of cutouts, and resulting in the spelling out of a little 3-letter word (meaningful amino acid sequence).

Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. Despite such variety, proteins also share several specific structural characteristics in their monomers, the . Structural similarities among amino acids make protein synthesis a uniform and regulated process; however, each amino acid contains a unique structural component as well. Specific differences between each amino acid interact to create unique three-dimensional protein structures. Combined, the similarities and differences between amino acids explain how cells can build a diverse pool of proteins from the same set of building blocks.

Knowing the importance of protein structure in determining function, how then is protein structure determined? To answer this, we must first ask how only twenty amino acids can create the diversity of proteins we see in living organisms. This diversity is easily explained by the way polypeptides form a sequence. Imagine creating a dipeptide using the twenty common amino acids. Twenty options exist for the first position, and twenty options exist for the second position of this two amino acid peptide. Math calculations tell us that we could synthesize four hundred different dipeptides! For every additional amino acid in a peptide, we multiply this number of options by twenty again. With more than one hundred amino acids in the average sequence, imagine how many different polypeptides may exist in nature!

Using a positive control template to verify protein synthesis can be useful when unfamiliar with in vitro transcription-translation protocols. We recommend wearing gloves and using nuclease-free tubes and tips to avoid introducing nucleases to your samples. Please keep all reagents on ice before and during the assembly of reactions and avoid multiple freeze-thaw cycles of the tubes. Reactions are typically 25 μl but can be scaled down or up, as needed. Reactions are usually assembled in nuclease-free 0.5 ml microfuge tubes.

Protein folding involves three layers of chemical interactions, termed secondary, tertiary, and quaternary structure. is created as hydrogen bonds form between nearby amino acids during protein synthesis. Hydrogen bonds in secondary structure involve the polar amino and carboxyl groups of amino acids, but do not involve R-groups. As the peptide chain continues to grow, interactions between amino acid side chains (R-groups) form the of a polypeptide. Side chains interact with one another by:
