(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).
However, we still know relatively little about how the structure of an enzyme controls which substrate is bound, how substrate orientation is enforced in the active site, and what factors are responsible for chemical specificity in the reactions that are catalyzed by a given enzyme.
