Certain structurally different polyisophthalamides containing pendent phthalimide groups were synthesized from 5- phthalimide isophthalic acid and aromatic diamines by the phosphorylation method.
Additionally, domain-modularity concepts bar certain structurally compact regions from having arisen by a single evolutionary event.
P-glycoprotein is responsible for the ATP-dependent export of certain structurally unrelated compounds including many chemotherapeutic drugs.
Through these searches we were able to identify around ten previously unknown families/superfamilies of domains containing the β-GF, including certain structurally distinctive variants.
For example, in vitro systems may be useful for certain structurally defined compounds and mechanisms of toxicity, such as organophosphorus compounds and delayed neuropathy, for which target cells and the biochemical processes involved in the neurotoxicity are well known.
Frequent fire can simplify forest structure, though topographic mitigation of fire effects could potentially preserve structurally more complex habitat within certain topographic locations of fire prone landscapes.
Perplexed by this trade-in of solid brick for a spindly steel skeleton, Chicago inspectors paused the construction of the Home Insurance Building until they were certain it was structurally sound.
Over the years, not only has Israel prohibited the emergence of a new Palestinian economy -- it structurally and systematically has made certain that even the buds of such a productive economy would never see the light of day.
Although C. jejuni PPK2 is structurally not related to PPK1, certain phenotypes are common to both PPK1 and PPK2, while others are not, suggesting that PPK1 and PPK2 contribute to overlapping but not redundant functions.
