The consequence for such aborted C 9 =C 10 isomerization is the release of energy over the polyene chain, affecting mostly C 8 and C 10, which elbow in the opposite directions relative to the C 20 methyl (Fig. 2b,c). WebOct 25, 2024 · An intramolecular interaction between the p53 transactivation and DNA binding domains inhibits DNA binding. To study this autoinhibition, we used a fragment of p53, referred to as ND WT, containing the N-terminal transactivation domains (TAD1 and TAD2), a proline rich region (PRR), and the DNA bindi …
WebThe large entropic driving force in polyelectrolyte complex coacervation observed in experiments is commonly believed to arise from the counterion release upon complexation between oppositely charged polyelectrolyte chains (61–63, 76, 83).However, this counterion-release mechanism can only explain the entropy dominance in the regime … WebCounterion release also plays an important role in the adsorption of flexible polyelectrolytes on flat surfaces 37 or the formation of complexes of such …
