The maximal affinity of ligands
Splet17. jun. 2009 · EGFR ligands differentially induce receptor internalization and recycling. To compare the ability of the different EGFR ligands to induce internalization of EGFR, we used the common approach of pre-binding ligand on ice, thereby looking at a synchronized wave of receptor internalization (7,14,15).We initially determined the incubation time necessary … Splet11. sep. 2024 · LE was originally developed in order to compare the maximal ligand-target affinity including small, nonhydrogen ligand cations or anions. This, in turn, determined that non-hydrogen atom count, namely HAC, was the natural normalizing measure. ... (1999) The maximal affinity of ligands. Proc Natl Acad Sci USA 96:9997–10002.

SpletHigh-affinity ligand binding implies that a relatively low concentration of a ligand is adequate to maximally occupy a ligand-binding site and trigger a physiological response. … SpletLigands with more than one potential donor atoms are known as ambidentate ligands. For example, thiocyanate ion (NCS –) which can bind to the central metal atom or ion with either nitrogen or sulfur atoms. Bridging ligands Bridging ligands is the one which is bound to more than one metal atom.
SpletThe idea for the sa metric is that the affinity more likely scales with the surface area of the molecule that can make interactions with the protein as opposed to the volume, which is what the number of heavy atoms is essentially measuring. The ln metric has no real physical grounds but seems to be a good fit to the Kuntz data. Splet03. mar. 2024 · The affinity between a protein and a ligand ought to be independent of the protein concentration, thus the KDobs values obtained by waterLOGSY at higher protein concentrations were overestimated.

From the original expression of the complex formation: The standard state free energy change, ΔG 0, for the process (i.e. starting with 1M everything) would be given as:. Since K d is the inverse of K f:. In this case, a negative value for DG 0 (indicating spontaneity) will occur when K d < 1.0. This will … Splet02. maj 2024 · The affinity of an enzyme or a protein transporter indicates the strenght of the binding of substrate/solute. ... K M is basically the concentration of substrate/ligand at which the rate of the reaction is half of the maximum rate ...
