High km affinity
WebAs Annemarie Honegger said, lower Km means that the enzyme has higher affinity for the substrate and vice versa. Thus, you will need less of your probe for an assay than you … WebVm = 17.5, Kd = 0.043, Km = 1.5, 1.6: high galactose affinity: Glucose transport in mammals. 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.

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. Web27 de dez. de 2024 · Numerical simulation using revised kinetic parameters revealed that MCT4, but not the related transporters MCT1 and MCT2, endows cells with the ability to export lactate in high-lactate microenvironments. In conclusion, MCT4 is a high-affinity lactate transporter with physiologically relevant affinity for pyruvate.
