The following is a list of notable proteins that are produced from recombinant DNA, using biomolecular engineering. [1] In many cases, recombinant human proteins have replaced the original animal-derived version used in medicine. The prefix "rh" for "recombinant human" appears less and less in the literature.
The words protein, polypeptide, and peptide are a little ambiguous and can overlap in meaning. Protein is generally used to refer to the complete biological molecule in a stable conformation, whereas peptide is generally reserved for a short amino acid oligomers often lacking a stable 3D structure. But the boundary between the two is not well ...
A tripeptide (example Val-Gly-Ala) with green marked amino end (L-valine) and blue marked carboxyl end (L-alanine) Peptides and proteins are often described by the number of amino acids in their chain, e.g. a protein with 158 amino acids may be described as a "158 amino-acid-long protein".
Mycoprotein prepared and served as a meat analogue. Mycoprotein (lit. "protein from fungus"), also known as mycelium-based protein or fungal protein, is a form of single-cell protein derived from fungi for human consumption.
If the amount of nitrogen is multiplied by a factor depending on the kinds of protein expected in the food the total protein can be determined. This value is known as the "crude protein" content. The use of correct conversion factors is heavily debated, specifically with the introduction of more plant-derived protein products. [20]
At the top level are all alpha proteins (domains consisting of alpha helices), all beta proteins (domains consisting of beta sheets), and mixed alpha helix/beta sheet proteins. While most proteins adopt a single stable fold, a few proteins can rapidly interconvert between one or more folds. These are referred to as metamorphic proteins. [5]
Recombinant proteins are widely used as reagents in laboratory experiments and to generate antibody probes for examining protein synthesis within cells and organisms. [4] Many additional practical applications of recombinant DNA are found in industry, food production, human and veterinary medicine, agriculture, and bioengineering. [4]
A conjugated protein is a protein that functions in interaction with other (non-polypeptide) chemical groups attached by covalent bonding or weak interactions. [ 1 ] Many proteins contain only amino acids and no other chemical groups, and they are called simple proteins.
