Enzymology is the study of enzymes, their kinetics, structure, and function, as well as their relation to each other.
In the diagram on the right, hexokinase is displayed as an opaque surface with a pronounced open binding cleft next to an unbound substrate (top) and the same enzyme with more closed cleft that surrounds the bound substrate (bottom). The enzyme changes shape by induced fit upon substrate binding to form an enzyme-substrate complex. Hexokinase has a large induced fit motion that closes over the substrates adenosine triphosphate and xylose. Binding sites in blue, substrates in black and Mg2+ cofactor in yellow.
A classification of enzymes includes
2. hydrases,
3. mutases,
4. desmolases,
5. other enzymes, and
6. polysaccharide-synthesizing enzymes.
Def. A molecule produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction, a "protein that catalyses a biological chemical reaction enzymes are biological catalyst that speed up the rate of a chemical reaction"[1] is called an enzyme.
Def. a science "that studies enzymes"[2] is called enzymology.
A "new enzymology develops around the organic liquids more favorable in the THz frequencies. ... The design of such microfluidic hioMEMS should answer to a good microfluidic and electromagnetic propagation, and should have an antiseptic character."[3]
