Low DO concentration exerts a competitive inhibition by AOB over NOB due to the higher half-saturation coefficient of DO affinity for NOB (Picioreanu et al. 1997).
The experimental rate could be better matched by assuming higher values for the diffusion coefficient of Ca2+, the affinity of the buffer for Ca2+, or the Hill constant for channel activation.
An unbiased evaluation of predictive models for the affinity coefficient of the Dubinin Radushkevich equation was performed.
For UVCLUSTER analyses, 10000 iterations, generating as many alternative topologies, and an affinity coefficient of 100 were used to estimate the "secondary distances" that are used to build the final dendrograms (see [ 15] for details on these parameters).
On the other hand, the mutations that cause the greatest loss of affinity leave the Hill coefficient unaltered, raising the possibility that the high affinity site(s) might be completely destroyed causing some low affinity site(s) to dominate the channel activation.
Based on their distribution coefficients, the affinity of activated carbon for metal ions follows the selectivity sequence expressed below.
Binding was confirmed in cells using pull-downs, while in vitro binding assays showed direct, high affinity (apparent dissociation coefficient of c. 0.25 nM) binding of Dp71d to IMPα/β.
In addition, it is possible to estimate the constants (binding affinity and hill coefficient) of one of the 13 reactions in the system.
The Hill Waud model in terms of SH intensity can be expressed as follows (detailed derivation in Supporting Information): 5where n is the Hill coefficient describing the affinity of the protein for its ligand when another ligand is already bound.
