Together, the docking results showed that SPGB3N adopted a binding mode that was consistent with other choline-containing substrates of hBChE, although the distance between the active site serine and the nerve agent phosphorus atom suggested that this precomplex was not reactant-like for the phosphonylation reaction.
The production of iso-butane is significant and was not seen with either reactant separately.
Curiously, species 1 c, 1 d, and 1 e all have an NH3 ligand, which was not present in the reactants.
As the acute-phase reactant CRP was not elevated in our cohort, the increased MIF levels in patients with pSS cannot be explained by differences in the extent of acute-phase response.
The polyubiquitin chain was formed when all reactants were added (E1, E2, E3, and ubiquitin), while, it was not detected if any of the reactants were excluded.
The symbol KD is used, instead of Km, solely to reflect the fact that the NA is not a reactant (i.e. it is not converted into products) but only a cofactor of the reaction, without implying any assumption on the nature of the microscopic rates contributing to the KD value itself.
Studying the hydroxynitrile lyase-catalyzed synthesis of cyanohydrins is particularly suitable to gain this understanding, since water is not a reactant in this versatile enantioselective reaction.
The higher percentage of glycerol (>40 %) was not attempted as mixing of the reactants was not homogeneous due to increase in the viscosity of the solution.
We also conducted additional analyses on a subgroup of RA patients, in whom laboratory data were available, to assess whether the severity of RA affects the risk of fracture, and observed an increased risk associated with positive RF and elevated acute phase reactants, although it was not statistically significant.
This catalyst was easy to recover, was not hydrated or carbonated, was not dissolved by the reactants or the products of the reaction, showed a high activity for the FFA esterification and presented high stability.
In some cases the addition of a substance that is not itself a reactant, called a catalyst, accelerates a reaction.
