In a certain enzyme-catalyzed reaction the following steps occur:

1. A phosphate group on substrate A is transferred to a side chain of an active site residue of the enzyme.

2. The dephosphorylated form of substrate A dissociates from the enzyme.

3. Substrate B enters the active site and is phosphorylated with simultaneous regeneration of the enzyme in its original form.
