Enzyme Classification

Nomenclature and Classification of Enzymes Naming the Enzymes Enzymes are generally named according to the substrate they complex with or the type of reaction they catalyze. The usual practice is to add suffix -ase to the name of the substrate involved. Thus, the enzyme cellulase, arginase and tyrosinase are named because their substrate cellulose, arginase and tyrosinase. But as the ...

Enzyme Inhibition

Enzyme inhibition types Competitive inhibitors bind reversible to the enzyme, preventing the binding of substrate. On the other hand, binding of the substrate prevent the binding of the inhibitor. Substrate and inhibitor compete for the enzyme. Competitive Inhibition In competitive inhibition, the inhibitor and the substrate compete for the enzyme (i.e., they cannot not bind at the same time). Often ...

Mechanism of Enzyme Action

Mechanism of Enzyme Action The molecules upon which an enzyme acts are called its substrate. For example, cellulose is broken down by enzyme cellulase, therefore cellulase is the substrate. Active Sites The active site of enzymes is a complex three dimensional-cavity into which the substrate molecule fits. At the active sites the enzymes work by lowering the energy of activation. ...

What Are Enzymes

Enzymes Enzyme are partly or entirely a protein that can tremendously increase the efficiency of a biochemical reaction and is generally specific for that reaction. The term enzyme (Gr. en = in + zyme = living) was first discovered by W. Kuhne in 1878 while working on fermentation. Nature of Enzymes – Physical Properties The enzymes are proteins wholly or partly. ...
