At an external pH below the pKa value (Lambert and Stratford 1999), the acetate predominantly assumes an undissociated lipophilic form and can permeate the plasma membrane by simple diffusion.
Indeed, circular dichroism (CD) studies of selected peptides associated with biological activities (Tables 1 and 2) indicate that they predominantly assume an α-helical conformation in water.
The high glycine content of gp76 would be expected to result in a highly flexible structure, and analysis by PsiPred [ 75] suggests the protein predominantly assumes random coil or beta strand conformation.
Genomic structural variation, including insertions, duplications, deletions, inversions and translocations of DNA, has long been known to be present in animal genomes [ 4, 5] but had predominantly been assumed to be to rare events and often associated with disease.
Greenland, a territory of Denmark with a predominantly Inuit population, assumed self-rule in 2009, giving it control of its resources.
Because the study area was predominantly residential, we assumed that each residence on the distribution network used the same amount of water.
A G-A mismatch in a GC-rich context exhibited a regular intrahelical structure and a high repair efficiency, while the same mismatch in an AT-rich context assumed predominantly a looped-out conformation and was poorly repaired.
