    • Enzymic half-site reactivity is observed in proteins composed of n identical subunits but which react with a substrate or an inhibitor with only n/2 subunits saturated with that ligand. Binding of the ligand to one site typically induces a conformational change of the second binding site, thereby rendering the second site inactive.
