And so ultimately we regenerate that enzyme and then we also form that hydrolyzed final product in which we now have a peptide bond that has been broken. And so this is the very quick step that takes place that accounts for this relatively steep slope. But as we reach the steady state conditions, as the intermediate concentration basically does not change what begins to happen is this begins to level off. And this describes the fact that the second step takes place much slower than that initial step. And so this is a two step catalytic mechanism that basically generalizes what takes place inside climate trypsin. So the first step is the fast oscillation step in which the Acyl group is added onto the enzyme and then the amide is released.
