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 [Continue]

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 [Continue]

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 [Continue]
