WebParticularly, functionalized proline residues were inserted at P2 to stabilize the β-turn like bioactive conformation, modulating the affinity. The most potent compounds displayed low/sub-nM potency against the 3CL pro of SARS-CoV-2 and MERS-CoV and inhibited viral replication of three human CoVs, i.e. SARS-CoV-2, MERS-CoV, and HCoV 229 in … Web14 de fev. de 2024 · High values of KM correspond to low enzyme affinity for substrate (it takes more substrate to get to Vmax ). What is the relationship between Km and enzyme affinity? Small Km means tight binding; large Km means weak binding. – Indicates how efficiently an enzyme selects its substrate and converts to product.
There are over 10 different types of glucose transporters; however, the most significant for study are GLUT1-4. GLUT1 and GLUT3 are located in the plasma membrane of cells throughout the body, as they are responsible for maintaining a basal rate of glucose uptake. Basal blood glucose level is approximately 5mM (5 millimolar). The Km value (an indicator of the affinity of the transporter pro… WebSolution. Verified by Toppr. Km is the concentration of substrate which permits the enzyme to achieve half Vmax. An enzyme with a high Km has a low affinity for its substrate and requires a greater concentration of substrate to achieve Vmax and vice versa. Enzyme a has high km and Enzyme b has low km. So, “enzyme b has high affinity for its ...

The Km in an enzymatic reaction is the substrate concentration at ... WebGLUT2 has high capacity for glucose but low affinity (high KM, ca. 15–20 mM) and thus functions as part of the "glucose sensor" in the pancreatic β-cells of rodents, though in human β-cells the role of GLUT2 seems to be a minor one. [7] It is a very efficient carrier for glucose. [8] [9] GLUT2 also carries glucosamine. [10]
Web8 de mai. de 2024 · Aug 5, 2009. #2. Km and Vmax are related to enzyme kinetics in a biological system. Km is the substrate concentration that is required for the reaction to occur at 1/2 Vmax. In other words, it is how much substrate is needed for the reaction to occur at 1/2 its max possible rate. Obviously Vmax is the maximum rate that the reaction can …
Web22 de jan. de 2013 · Km is the concentration of the substrate at which V = 1/2Vmax. This means that the lower Km is, the less substrate you need to reach 1/2Vmax.
