Bisphosphonates are retained over time in the skeleton and may exert long-term effects and their biological half-lives may vary and depend on the rate of bone turnover, potency, and binding affinity of each one to bone.
Whereas MeCP2 bound to all methylated promoters, MBD2 had only binding affinity to one of the promoters studied [ 30].
One of the key end-points used in the screening of new molecules, beside the antiproliferative activity, is the binding affinity of the drug to one or another of the specific binding sites present on tubulin.
We note that a SNP allele can be found with an increase of TF binding affinity for one TF and a decrease for another.
Computing the binding affinity of a protein ligand complex is one of the most fundamental and difficult tasks in computer-aided drug design.
The increase in kcat,app values for the R153A mutant was unexpected and may be related to a decrease in the binding affinity of the AANATA for CoA-SH, one product of the reaction.
However, studies that characterized how nucleotides allosterically regulate the DNA binding affinity of ISW2 have yielded conflicting results: while one study showed that ADP reduced the DNA binding affinity of ISW2, another study showed that ADP had no effect on DNA binding affinity.
Figure 2 plots the trajectories of the four Markov chains for the relative binding affinity of TB to T (RBATB_T), which is one of the 26 calibrated model parameters.
Two β2 mutations, α3β2 (F119Q) and α3β2 (T59K), strongly enhanced the binding affinity of LvIA (IC50 0.58 nmol/L and IC50 0.96 nmol/L, respectively), and one β2 mutation, α3β2 (V111I), substantially reduced the affinity (IC50 126 nmol/L) (Zhangsun et al., 2015).
However, the binding affinity of PDZ domains is known to be regulated through allosteric interactions49.
