http://chemistry.elmhurst.edu/vchembook/573inhibit.html 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.

WebSeveral types of protein biosynthesis inhibitors are discussed in this section and are summarized in Figure 14.11. Protein Synthesis Inhibitors That Bind the 30S Subunit. Aminoglycosides are large, highly polar antibacterial drugs that bind to the 30S subunit of bacterial ribosomes, impairing the proofreading ability of the ribosomal complex. WebExamples include methotrexate (used in chemotherapy and in treating rheumatic arthritis) and the protease inhibitors used to treat HIV/AIDS. Since anti-pathogen inhibitors generally target only one enzyme, such drugs are highly specific and generally produce few side effects in humans, provided that no analogous enzyme is found in humans. nellie\\u0027s oxygen brightener vs oxicleanWebDrugs of this class are competitive inhibitors of α-glucosidase enzymes in the brush border of enterocytes, lining the intestinal villi. Thereby, they prevent the final step of carbohydrate digestion (i.e., cleavage of disaccharides and oligosaccharides into monosaccharides). As a result, glucose absorption is delayed. nellie\u0027s kitchen hallowell maine

Competitive Inhibition - Process, Examples and Outcome

WebExample : The enzyme of Krebs cycle succinate dehydrogenase catalyzes a reaction to convert succinate into fumarate. Malonate acts as a competitive inhibitor because it has a similar structure to succinate, the inhibitor binds to the active site of succinate dehydrogenase and inhibits the reaction.
