Sentence examples for solution of stigmatellin from inspiring English sources
A stock solution of stigmatellin was prepared in absolute ethanol.
The intersubunit disulfide bond formation also decreases the rate of stigmatellin induced reduction of ISP in the fully oxidized complex, suggesting that an endogenous electron donor comes from the vicinity of the b position in the cytochrome b.
On the other hand, addition of stigmatellin lowers the level so that it approaches the level of stigmatellin-treated wild-type cytochrome bc1.
Figure 3b shows the plots obtained with ascorbate- and dithionite-reduced cytochrome bc1 in the presence of stigmatellin.
We thus observe that different samples of native cytochrome bc1 in the absence of stigmatellin produce distinct dipolar decay curves, but all of the curves fall between the calculated boundary levels defined for the Qo and c1 positions.
Crystals formed from this mutant complex, in the presence of stigmatellin, diffract X-rays up to 2.9 Å resolution.
The presence of Stigmatellin Y was predicted with monoisotopic neutral mass of 484.2825 Da.
To illustrate this, a correction accounting for the effect of stigmatellin was included in Figure 8 (gray part of the bars for stigmatellin).
In order to examine this contribution, the spin−lattice relaxation rates for dithionite-reduced samples in the presence of stigmatellin at 15 and 19.5 K were measured by three different methods.
In all other states of native enzyme (i.e., in the absence of stigmatellin), the FeS head domain moves in and out of the Qo site, which shifts its average equilibrium position.
Thus, the observed differences in the experimental dipolar decays of samples of native cytochrome bc1 in the absence of stigmatellin must originate mainly from the different contribution of the occupancy of position D in respect to the occupancy of the other positions.
