For the first time, researchers have successfully used computational simulations to modify an enzyme’s structure to increase the optimum temperature of a reaction. Researchers at Uppsala University ...

This article describes a simple method to determine the optimum pH for the activity of one enzyme in a coupled enzyme assay. Decoupling of the two-step reaction is achieved by heat denaturing the ...

Enzymes are also involved in the building up of chemical molecules elsewhere in the body. In an organism, the active site of each enzyme is a different shape. It is a perfect match to the shape of the ...

Enzymes have an optimum temperature at which they are most catalytically active. Above that temperature, they become less active. Previously, it was thought that this was because enzymes unfolded ...

Different enzymes contain up to 20 different amino acids linked together to form a chain which then folds into the globular enzyme shape. Enzymes have active sites which only match specific substrates ...

Enzymes can be utilized in numerous fields, such as enzymes for diagnostics and enzymes for cancer treatment. Due to the action of the enzyme, the chemical reaction in the organism can be effectively ...

How enzymes -- the biological proteins that act as catalysts and help complex reactions occur -- are 'tuned' to work at a particular temperature is described in new research. How enzymes -- the ...
