One possible assumption is that these perturbations result from a stochastic variability in the gene expression levels.
Since 3.2 Å represents the distance of a hydrogen bond and no proton is expected to associate with OE2 of Glu453 and OE1 of Glu406 under the crystallization pH 7.5, a possible assumption might be that Glu406 in the PDE9Q453E mutant locally sequesters a hydrogen atom and thus exists in the protonated form.
Another possible assumption is LOCF.
The simplest possible assumption is essentially an assumption of non-interaction (statistical independence).
First, we determine the relative expectations of the play choices with our best possible assumptions about the team's relative strengths and weaknesses.
He also tested many other possible assumptions, but none of them produced an age for proto-Indo-European anywhere near the date of 6,000 years ago favored by linguists.
