(PDB: 9LYZâ) In biology, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of residues that form temporary bonds with the substrate (binding site) and residues that catalyse a reaction of that substrate (catalytic site).
The role of the enzyme is to reduce the activation energy, by bringing specific molecules together, rather than relying on random collisions) Action on specific Substrates. Enzymes are substrate specific, meaning only one particular substrate molecule can work with one particular enzyme. This is due to the reciprocally shaped active site. Since the enzyme is never chemically alter by a reaction, it can be reused in subsequent reactions â enzyme controlled reactions are always reversible.
