While it is unlikely that the nickel concentration in an E. coli cell would ever be high enough that the NikR structure depicted in Figure 2b, with 14 surface nickels, would ever be realized, all sites identified here are easily accessible to excess nickel ions, even if NikR is already bound to DNA.
These data indicate that SM depletion first releases cholesterol into a PFO-accessible pool, and then the excess cholesterol is transported to the ER.
The large base only deprotonates the more accessible hydrogen, and the low temperatures and excess base help avoid equilibration to the more stable alternate enolate after initial enolate formation.
Blizzard's best hits take genres and concepts that previously existed, and relentlessly refine them, sanding the rough edges off the concepts and trimming excess fat until they emerge sleek, accessible – and, inevitably, extremely popular.
The SQR assays described so far measure the maximal enzymatic activity of complex II, as the complex is made accessible in permeabilized mitochondria and exposed to an excess of substrates.
The enzyme-accessible xylan was then completely digested by adding excess GH family 10 (GH10) β-xylanase (CjXyn10A), and the released xylo-oligosaccharides quantifed by DASH, using QS.
The membrane lipid composition determines how much cholesterol can be complexed within the inaccessible pool, and cholesterol in excess of that threshold partitions into the accessible pool.
Though we certainly do not celebrate the ridiculous excess of these teenage television characters, making art accessible is something we believe is vital in getting people into the doors of our cultural institutions, studying art history and creating art.
While these sites are solvent accessible, they are the most buried of all the observed excess nickel binding sites.
To dissect the effect of AUL12 on respiration, we directly tested maximal RC complex activity under conditions where complexes are made accessible in mitochondria or permeabilized cells, and exposed to an excess of substrates.
