In addition, the Haddock prediction revealed a potential nucleic acid binding site that binds ds, ssDNA and RNA well. The binding site is positioned at the close contact of HTH and S5D2L domains that form an electropositive groove. This finding is in agreement with previous predictions7 and ...
Consider the acid-base nature of potassium nitrate, KNO_3, when it is dissolved in water. Would an aqueous solution of potassium nitrate be acidic, basic, or neutral? In which solution (acidic, basic, neutral water, or doesn't matter) is potassium bromide most soluble? a....
In such experiments, the incubation mixture was found always to contain ferulic acid present as an impurity in the commercially provided feruloyl-CoA. Since ATP and NAD þ were not required as cofactors in these reactions, we conclude that vanillin synthase is NATURE COMMUNICATIONS | 5:4037 | ...
In an aldol condensation,an enolate ion reacts with a carbonyl compound in the presence of acid/base catalyst to form a β-hydroxy aldehyde or β-hydroxy ketone, followed by dehydration to give a conjugated enone. It is a useful carbon-carbon bond-forming reaction. What is meant by aldol ...
How are Ka and Kb values of an acid and base used to determine the acidic or basic nature of their aqueous salt solution? Applying this process, determine if a salt solution of NH4ClO2 is acidic, basic, or neutral. Calculate the pH of asparagine wit...
Leucine zipper (ZIP) motifs are distinguished by a leucine residue positioned every seventh amino acid, with similarly spaced hydrophobic residues (Fig. 1A). The motif assumes an alpha-helical conformation, with leucines aligning on one face of the helix in the “d” position and hydrophobic ...
Amazon and began taking 2 drops a day in a glass of warm water first thing in the morning on an empty stomach, monday through friday with the weekend off. My wife did the same. Sure enough within a few weeks my digestion is back to where it was as a teenager, and acid reflux is ...
STIM1 is a 685-aminoacid type I transmembrane protein located in the endoplasmic reticulum (ER), with an essential role in Ca2+mobilization and signaling. The Ca2+-sensitive EF-hand domain at the N-terminus rules the conformational change in STIM1 when the intraluminal Ca2+concentration drops ...
Pure DNA were finally loaded and run on a 1% agarose gel at 80 V in runningbuffer (89 mmol/LTris-acetate, 2 mmol/L Na2EDTA, and 89 mmol/L boric acid), stained with ethidium bromide, and photographed. The samples were run in tandem with a DNA molecular weight ladder (Life ...
LAT1, an amino acid transporter in cell membranes, acquires leucine from the extracellular environment and is dependent on intracellular glutamine; the obtained leucine then participates in metabolic processes, such as mTOR activation. Of the two glutaminase enzymes catalysing the conversion of glutamine...
