Enzyme kinetics involves the measurement of the rate at which chemical reactions that are catalyzed by enzymes occur. Knowledge about the kinetics of an enzyme can reveal useful information about its ...

Enzymology is the study of enzymes and enzyme-catalyzed reactions. Enzymes are biological catalysts that accelerate the rate of biological reactions. They can also perform multiple reactions ...

It is well known in physics and chemistry that equal charges repel each other, while opposite charges attract. It was long assumed that this principle also applies when enzymes -- the biological ...

Measuring Enzyme Kinetic Parameters with the ITC Universal Enzyme Assay Method Enzymes are important in drug discovery and development since they constitute approximately one-half of all known drug ...

Enzymes play a key role in cellular metabolic processes. To enable the quantitative assessment of these processes, researchers need to know the so-called “turnover number” (for short: k cat) of the ...

Light of specific wavelengths can be used to boost an enzyme's function by as much as 30 fold, potentially establishing a path to less expensive biofuels, detergents and a host of other products.

Chemists have long dreamed of mimicking nature’s precision, and now, thanks to a repurposed enzyme, they’ve taken a leap closer. Researchers at the University of Basel have successfully combined a ...

The three tobacco (Nicotiana tabacum L.) S-adenosyl-L-methionine: o-diphenol-O-methyl-transferases (OMTs; EC 2.1.1.6) were purified to homogeneity by affinity chromatography on adenosine-agarose.
