"GLUTs are integral membrane proteins that contain 12 membrane-spanning helices with both the amino and carboxyl termini exposed on the cytoplasmic side of the plasma membrane. GLUT proteins transport glucose and related hexoses according to a model of alternate conformation, which predicts that the transporter exposes a single substrate binding site toward either the outside or the inside of the cell. Binding of glucose to one site provokes a conformational change associa… " - High km low affinity

Web7 de jul. de 2024 · An enzyme with a high Km has a low affinity for its substrate, and requires a greater concentration of substrate to achieve Vmax.” What is Km in enzyme kinetic? Km (also known as the Michaelis constant) – the substrate concentration at which the reaction rate is 50% of the Vmax. WebBinding affinity is the strength of the binding interaction between a single biomolecule (e.g. protein or DNA) to its ligand/binding partner (e.g. drug or inhibitor). Binding affinity is typically measured and reported by the equilibrium dissociation constant (K D ), which is used to evaluate and rank order strengths of bimolecular interactions.
