Uncompetitive Inhibition - Biochemistry

Uncompetitive inhibition occurs when an inhibitor binds to an allosteric site of a enzyme, but only when the substrate is already bound to the active site. In other words, an uncompetitive inhibitor can only bind to the enzyme-substrate complex.

Uncompetitive inhibition occurs when an inhibitor binds to an allosteric site on the enzyme, but only when it is an enzyme-substrate complex. Because the inhibitor binds to the enzyme-substrate complex and then changes the enzyme's conformation, it makes it incredibly difficult for the substrate to become unbound from the enzyme. Thus, the apparent affinity of the substrate for the enzyme is dramatically increased. A decrease in represents an increase in affinity. still decreases when an uncompetitive inhibitor binds.

With uncompetitive inhibitors, the inhibitor binds to a site separate from the binding site of the substrate. This can occur even while the substrate is bound to the enzyme, blocking the process and reduce the catalysis of the enzyme.

This will result in the reduction of Vmax because the enzymes ability for catalysis is being reduced by the binding of inhibitor to the enzyme-substrate complex. Km does not change because the substrate and the uncompetitive inhibitor bind to different sites.

The correct answer is that uncompetitive inhibitors of enzymes only affect enzymes that act on multiple substrates. Uncompetitive inhibitors bind to the enzyme-substrate complex only, not to the free enzyme. They distort the active site to prevent the enzyme from being catalytically active without actually blocking the binding of the substrate. This cannot occur with an enzyme that only acts on a single substrate at a time. Adding more substrate and lowering the amount of free enzyme available both apply to competitive inhibitors, which bind to free enzymes and block the substrate-binding site of the enzyme. Uncompetitive inhibitors do decrease the apparent KM on a Lineweaver-Burke plot, but they also lower the apparent VM.
