The name of an enzyme usually refers to the type of biochemical reaction it catalyzes. For example, proteases break down proteins, and dehydrogenases oxidize a substrate by removing hydrogen atoms.

Enzymes have active sites which only match specific substrates. The diagram shows how this works. In this example, the enzyme splits one molecule into two smaller ones, but other enzymes join ...

Enzyme activity measures how fast an enzyme can change a substrate into a product ... and enzyme activity will slow down if conditions are not ideal. For example, your normal body temperature is ...

In an organism, the active site of each enzyme is a different shape. It is a perfect match to the shape of the substrate molecule, or molecules. This is essential to the enzyme being able to work.

There are numerous examples in the literature of promiscuous enzymes, including members of the short-chain dehydrogenase/reductase family that bind similar substrates and generate alternative ...

Specific examples of enzymes currently being investigated are listed below ... enzymes in each of the catalytic steps of its reaction such as Michaelis complexes (substrate bound complexes), ...
