And because of that, because this inhibitor resembles the transition state much more than it does that actual substrate molecule, this will be a much more potent, much better inhibitor. In fact, this molecule here, the transition state analog, parole two carboxylic acid binds 160 times more likely to the enzymes active side, to the proline raysimase active side than the proline molecule itself. And so if given a chance, this will be much more likely to bind into the active side than this substrate molecule or this substrate molecule. Another example is shown on this side of the board. So the enzyme methyl Thio adenosine nucleusidase is basically the enzyme that catalyzes the hydrolysis of the bond between this carbon on the sugar molecule and this nitrogen on the base. And this reaction is known as deadenylation.
