On December 31, 2020, Ben Imeddourene, A.; Zargarian, L.; Buckle, M.; Hartmann, B.; Mauffret, O. published an article.Application of 65-71-4 The title of the article was Slow motions in A·T rich DNA sequence. And the article contained the following:
In free B-DNA, slow (microsecond-to-millisecond) motions that involve equilibrium between Watson-Crick (WC) and Hoogsteen (HG) base-pairing expand the DNA dynamic repertoire that could mediate DNA-protein assemblies. R1ρ relaxation dispersion NMR methods are powerful tools to capture such slow conformational exchanges in solution using 13C/15N labeled DNA. Here, these approaches were applied to a dodecamer containing a TTAAA element that was assumed to facilitate nucleosome formation. NMR data and inferred exchange parameters assign HG base pairs as the minor, transient conformers specifically observed in three successive A·T base pairs forming the TAA·TTA segment. The abundance of these HG A·T base pairs can be up to 1.2% which is high compared to what has previously been observed Data analyzes support a scenario in which the three adenines undergo non-simultaneous motions despite their spatial proximity, thus optimizing the probability of having one HG base pair in the TAA·TTA segment. Finally, revisiting previous NMR data on H2 resonance linewidths on the basis of our results promotes the idea of there being a special propensity of A·T base pairs in TAA·TTA tracts to adopt HG pairing. In summary, this study provides an example of a DNA functional element submitted to slow conformational exchange. More generally, it strengthens the importance of the role of the DNA sequence in modulating its dynamics, over a nano- to milli-second time scale. The experimental process involved the reaction of 5-Methylpyrimidine-2,4(1H,3H)-dione(cas: 65-71-4).Application of 65-71-4
