Active site

(Science: chemistry) A specific region of an enzyme where a substrate binds and catalysis takes place (binding site). The part of an enzyme or antibody where the chemical reaction occurs.A structural element of protein that determines whether the protein is functional when undergoing a reaction from an enzyme. this structural element will be accordingly shaped to the structure of the enzyme at work on it.
