WebA potent inhibitor (benzodiazepine-competitive factor I, BCF-I) was discovered in the fraction containing substances with molecular weights from 40,000 to 70,000. Equilibrium binding … In competitive inhibition of enzyme catalysis, binding of an inhibitor prevents binding of the target molecule of the enzyme, also known as the substrate. This is accomplished by blocking the binding site of the substrate – the active site – by some means. The Vmax indicates the maximum velocity of the reaction, while the Km is the amount of substrate needed to reach half of the Vmax. Km …

WebJan 22, 2009 · COMPETITIVE INHIBITION. Competitive inhibitors affect the slope of a Lineweaver–Burk plot but do not alter the y-intercept (Fig. 2a). Therefore, a competitive inhibitor only binds to the enzyme at very low concentrations of substrate (i.e., an effect on V max /K m, which is the reciprocal of the slope). Weban inhibitor molecule binds to the active site of the enzyme this stops the substrate from binding Inhibitor molecules can compete with the substrate because they have a similar …
