Abstract

Binding of a substrate to an enzyme is the first step of the interaction between substrate (ligand) and enzyme molecules that leads to the formation of an intermediate substrate–enzyme complex. The formation process is controlled mainly by diffusion and requires a structural complementarity between the enzyme and ligand.
