[Derivation of a velocity equation for a reaction model witwh two binding sites for acetylcholinesterase]

The authors suggest a kinetic model with two binding sites for acetylcholinesterase; it is suitable to study particular enzyme forms that show a kinetic pattern which cannot be explained by the model with a single binding site of Krupka and Laidler. The velocity equation was obtained using the algorithm of King and Altman and carrying out elementary calculations.
