The phrase "alteration of active" is not correct and does not convey a clear meaning in written English.
It may be intended to describe a change or modification related to something being active, but the phrasing is awkward and unclear.
Example: "The alteration of active processes in the system led to unexpected results."
Alternatives: "modification of active" or "change in active".
We neglected by the kinetics for the channels of active transport due to the assumption that the kinetics of alterations of active transport are much faster that the characteristic alteration times of passive transport (equation (32) for the Ca2+ currents).
These hydrothermal minerals are commonly found in acidic alteration zones of active geothermal areas and sulfur fumaroles (e.g., Utada 1980; Hedenquist et al. 1996).
That is, the aim has not been to reproduce the particular experimental results at hand, as might be achieved with enough alterations of active-site models or the underlying quantum chemical methods.
It might, for example, reduce an enzyme's activity by 1% due to a subtle alteration of the active site or cause 1% of the protein to fail to fold correctly.
Apparently, the presence of an inserted domain within the AvrB β-hairpin, combined with an alteration of several active site motif residues hinders sequence recognition.
This alteration of the active site is reflected in the changes observed in the kcat,app and Km,app values for the S182A, S186A, and S182A/S186A mutants.
Taken together, the present results demonstrate that the anti-carcinogenic effects of FCY may be enhanced compared to those of CY due to the alteration of its active components by bacterial fermentation.
Loss of activity may arise from both reversible and irreversible alteration of the active-site Sec residue, but as the assessment of enzyme activity involves the use of reducing species (which may repair reversible damage), the observed loss of enzyme activity is believed to arise from irreversible modification of the enzyme structure.
Surface-enhanced resonance Raman scattering (SERRS) measurements in combination with AC and EIS, performed on the same electrode sample, proved that the CYP2D6 is immobilized on the HBM without evident alterations of its active site and without significant perturbations of the bilayer architecture.
Beyond the CXXCH rigidity, other alterations of the active site, likely linked to the increased rigidity of the loop, contribute to the change in reduction potential.
