Enzyme & Protein Engineering

Protein engineering is varying the structure of a protein to perk up or amend its properties. This unit summarizes concepts for protein engineering using rational design, directed evolution, and combinations of them. Different strategies are offered for identifying the best mutagenesis method, how to make out desired variants by screening or selection. This should enable researchers to choose the most hopeful tools to solve their protein engineering challenges. It is the process of mounting useful or valuable proteins. It is a young discipline, through much research taking place into the sympathetic of protein folding and recognition for protein design principles. There are two general strategies for protein engineering, 'rational' protein design and directed evolution. Using computational methods, a protein with a novel fold has been designed. The engineering of fusion proteins has yielded rilonacept, a pharmaceutical which has secured FDA approval for the healing of cryopyrin associated periodic syndrome. The prospects for protein engineering, including the roles of x-ray crystallography, chemical synthesis of DNA, computer modeling of protein structure and folding. It is now possible to stab to modify many different properties of proteins by combining information on crystal structure and protein chemistry with artificial gene synthesis. Such techniques tender the potential for altering protein structure and function in ways not possible by any other method.
