Comparing the cefotaxime-bound CTX-M-14 mutant structures with a previously published structure of the CTX-M-9 S70G mutant complexed with cefotaxime (PDB ID: 3HLW) showed an RMSD of 0.21 Å for the Cα atoms in the active site for the single mutant, 0.21 Å for the double mutant, and 0.20 Å for the triple mutant, indicating that there are no major displacements of active site residues.
This study revealed that hydrophobic residues are exposed while polar residues are buried during the activation process, which is caused by a displacement of the active site helix.
The experimental machine is characterised by the implementation of a force compensation system applied on the displacement of the active magnetic regenerator (AMR).
Displacement of the active site isostere by test compounds resulted in lowered intensity of PS1 and Nct bands on the immunoblots.
Interestingly, in the presence of exogenous APP substrate added to the extracts, we were able to detect displacement of the active site isostere at concentrations above the IC50 for Aβ inhibition by the compound.
Comparing the results to the outcome of a previous experimental study, the maximum rotational displacement of Nobel Active (hexagon) in the experiment is higher than the results for polygonal indices [ 16] and hexagonal indices in other studies [ 12, 13, 23].
In agreement with Bonferoni et al. [ 19], these data can be interpreted as the effect of the ionic competition between the drug and the cations in solution for the interaction with the polymer; this competition determines a displacement of the active ingredient from the complex once the latter is in a solution containing ionic species, thus facilitating the drug release.
The model for oil displacement by solutions of active reagents in hot water has been also analyzed.
Based on this model, the incompatibility of the transverse displacements of the active constraining layer and the host beam is investigated.
Displacement of p21Cip1 from active cyclin D1/CDK4 complexes allows p21Cip1 to bind and inhibit CDK2 activity, thereby inhibiting progression through G1 and into S phase (Sherr and Roberts, 2004).
