When "G" (AAA GTTT) is substituted by "I" (inosine) (AAA ITTT) at the minor groove binding site, the binding affinity decreases by 30-fold (KD = 10 nM) as would be expected for disruption of hydrogen bonding between the azabenzimidazole and G- NH2.
On the other hand, Hg2+ showed strong binding affinity to fresh DOM (L-1) and binding affinity decreased as the age of leachate increased.
When shear flow was applied to detach adherent cells, adhesive failure (ligand bond breakage) was favored over cohesive failure (membrane rupture), as the SA binding affinity decreased.
PHD1KDM5A binds the N-terminal tail of histone H3 with a preference for unmodified H3, and binding affinity decreases with an increase in H3K4 metH3K4tion40.
It can be observed that, at physiological pH, the binding affinity decreases.
By contrast, the apparent binding affinity significantly decreased when helices CD were present (Fig. 3D, green upward triangles, EC50 = 45.5 ± 3.8 nM [n = 3] for ABCD# [ABCD-A343D/ABCD-S511D], compared to 9.1 ± 0.1 nM for ABCD; supplemental Table 1).
Mutants of this design, in which one ligand was removed at a time (by substitution with Ala) to generate an open coordination site, were also tetrahedral, although the Co II) binding affinities were all decreased by at least 1 order of magnitude.
This reduced availability effectively lowers binding affinities by decreasing protein binding rates.
N59D uniquely causes PEP binding affinity to decrease, while having little effect on the binding affinity of MgADP.
In addition, the binding affinity of peroxidase was decreased by immobilizing it on graphene (graphane) oxide by electrostatic interactions [8].
