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.
The production of these amino acids is due to Corynebacterium glutamicum and fermentation. C.glutamicum was engineered to be able to produce L-lysine and L-Glutamic acid in large quantities. [7] L-Glutamic acid had a high demand for production because this amino acid is used to produce Monosodium glutamate (MSG) a food
Function: Amylase is an enzyme that is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates to be turned into simple sugars that will be easier to absorb. Clinical Significance: Amylase also has medical history in the use of Pancreatic Enzyme Replacement Therapy (PERT). One of the components is ...
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.
Ribbon diagram of a protease (TEV protease) complexed with its peptide substrate in black with catalytic residues in red.(. A protease (also called a peptidase, proteinase, or proteolytic enzyme) [1] is an enzyme that catalyzes proteolysis, breaking down proteins into smaller polypeptides or single amino acids, and spurring the formation of new protein products.

Aminopeptidases in the gastrointestinal tract, such as APN and APA, are essential for the digestion of dietary proteins. They facilitate the absorption and utilization of amino acids by cleaving them from the N-terminus of peptides. [12] These enzymes also play a role in the metabolism of bioactive peptides, including hormones and growth factors.
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.
In enzymology, an aminoacylase (EC 3.5.1.14) is an enzyme that catalyzes the chemical reaction. N-acyl-L-amino acid + H 2 O ⇌ carboxylate + L-amino acid. Thus, the two substrates of this enzyme are N-acyl-L-amino acid and H 2 O, whereas its two products are carboxylate and L-amino acid.
