Medicinally, microbes can be used for creating antibiotics in order to treat infection. Microbes can also be used for the food industry as well. Microbes are very useful in creating some of the mass produced products that are consumed by people. The chemical industry also uses microorganisms in order to synthesize amino acids and organic solvents.
The commercial production of amino acids usually relies on mutant bacteria that overproduce individual amino acids using glucose as a carbon source. Some amino acids are produced by enzymatic conversions of synthetic intermediates. 2-Aminothiazoline-4-carboxylic acid is an intermediate in the industrial synthesis of L-cysteine for example.
Industrial enzymes are enzymes that are commercially used in a variety of industries such as pharmaceuticals, chemical production, biofuels, food and beverage, and consumer products. Due to advancements in recent years, biocatalysis through isolated enzymes is considered more economical than use of whole cells.
It has been used to improve the function of many enzymes for industrial catalysis. [2] It is also a product and services market, with an estimated value of $168 billion by 2017. [3] There are two general strategies for protein engineering: rational protein design and directed evolution. These methods are not mutually exclusive; researchers will ...
Aminoacylases have been used for the production of L-amino acids in industrial settings since the late 1950s. [18] Since aminoacylases are substrate specific for N-acyl-L-amino acids and not N-acyl-D-amino acids , aminoacylases can be used to reliably take a mixture of these two reactants and only convert the L enantiomers into products - which ...
It usually consists of three to four amino acids, while other amino acids within the protein are required to maintain the tertiary structure of the enzymes. [2] Each active site is evolved to be optimised to bind a particular substrate and catalyse a particular reaction, resulting in high specificity. This specificity is determined by the ...
In some enzymes, no amino acids are directly involved in catalysis; instead, the enzyme contains sites to bind and orient catalytic cofactors. [31] Enzyme structures may also contain allosteric sites where the binding of a small molecule causes a conformational change that increases or decreases activity.
Artificial enzymes based on amino acids or peptides have expanded the field of artificial enzymes or enzyme mimics. For instance, scaffolded histidine residues mimic certain metalloproteins and enzymes such as hemocyanin, tyrosinase, and catechol oxidase. [3] Artificial enzymes have been designed from scratch via a computational strategy using ...
