Tetanus is also commonly called lockjaw, because the infection primarily causes muscle contractions in the jaw and neck, but can eventually spread to other parts of the body. Without treatment, tetanus infection can be life-threatening.
Competitive inhibitors. The inhibitor (I) competes with the substrate (S) for the enzyme active site (also known as the S-binding site). Binding of either of these molecules in the active site is a mutually exclusive event. The substrate and inhibitor share a high degree of structural similarity.
Enzyme - Inhibition. 1  Enzyme reaction rates can be decreased by various types of enzyme inhibitors. 2  A competitive inhibitor and substrate cannot bind to the enzyme at the same time. 3  A non-competitive inhibitor binds to a site other than where the substrate binds.
