What is an emzyme.

Enzymatic catalysis depends upon the activity of amino acid side chains assembled in the active centre. Enzymes bind the substrate into a region of the active site in an intermediate conformation. Often, the active site is a cleft or a pocket produced by the amino acids which take part in catalysis and substrate binding.
