However, inactivation of F397H by halide especially at low pH was observed during turnover.
The increased stability could be a result of the hydrophobic nature of the polymer film, which may stabilize the integrity of the complex during turnover.
None of the intersubunit cross-links, which had been designed across the entire interface, affected the glutamate transport activity, indicating that the subunit interfaces are rigid during turnover.
The combination of structural and biochemical data has allowed us to assign key residues and identify the conformation of the carbohydrate during turnover.
Manganese catalases contain a binuclear manganese complex as their catalytic active site rather than a heme, and cycle between Mn2 II,II) and Mn2 III,III) states during turnover.
Mutation of an active site residue Ser402 to Ala (S402A), a residue proposed to be brominated during turnover, caused a decrease in its activity, however it still catalyses efficiently the oxidation of both chloride and bromide.
According to this mechanism, two pump modules are driven by two conformational strokes that are generated by stabilization of the anionic forms of semiquinone and ubiquinol that are formed in the peripheral arm of complex I during turnover.
Specifically, a technique called valence-to-core x-ray emission spectroscopy (XES) is particularly well-suited for uncovering important information about the enzyme's structure during turnover, though this method had never before been used to study a pathway of enzyme intermediates.
The extracellular part of Notch1 and Notch2 (like other Notch receptors) is very large and includes thirty-nine disulfide-bonded domains (36 EGF-like repeats and 3 LNRs) that are expected to require reduction before becoming sensitive to proteolytic degradation during turnover.
As postulated in reactions 2 and 3, HOCl/ OCl is formed during turnover.
Intermediates II and III do not accumulate during turnover of PCP.
