Groundwater apparent age is relatively young (0 5 yr) based on tritium helium analysis, but whole-aquifer turnover time calculations are an order of magnitude longer (20 23 yr), suggesting changes in groundwater may lag behind changes in land management by years to decades.
Therefore, calculations of turnover with linear regression models are inevitably difficult to perform when induction systems are utilized.
Single turnover kinetic experiments and calculations suggest that a conformational change in the enzyme occurs prior to C S bond formation although no evidence for this has been noted in any of the crystal structures solved to date.
In numerous preparations of recombinant yeast ADH1 in our laboratory, we used titration with NAD+ in the presence of 10 or 100 mM pyrazole to determine the concentration of active sites for calculation of turnover numbers.
Regardless of whether factoring into the calculation the turnover cost for women with breast cancer, there is a greater potential financial gain related to eliminating a disparity in asthma medications than there is for eliminating a disparity in mammography rates.
This is key to accurate calculation of protein turnover rates; other heavy isotope labeling approaches require complex calculations to indirectly estimate and compensate for changes in precursor pool enrichment (Price et al., 2010, 2012; Kim et al., 2012).
The calculation of the turnover frequencies (TOFs) enables to show that, among all the samples studied, Ph-PMO-PrSO3H exhibit the higher catalytic activity.
Fig. S2 Topograph calculation of protein turnover rate and peak alignment for isotopomer abundance.
Calculation of the turnover rate (kcat) of the enzyme was not done due to the high level of recombinant glycosylation of CmINV, making accurate molecular weight determination misleading.
The concentration of Nox4 in cell lysates was estimated using Western blotting and allowed calculation of a turnover of ∼200 mol of H2O2 mol−1 (mof of Nox4)−1.
