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 ...

Life has evolved over billions of years, adapting to the changing environment. Similarly, enzymes—proteins that speed up biochemical reactions (catalysis) in cells—have adapted to the habitats of ...

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 ...

Binding between potato tuber invertase and its endogenous inhibitor followed second-order reaction kinetics. Binding rates were diminished by the presence of various inorganic salts, MgCl2 being ...

The Royal Society is a self-governing Fellowship of many of the world's most distinguished scientists drawn from all areas of science, engineering and medicine, and is the oldest scientific academy in ...

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 ...
