Phosphodiester bond rotation
WebMar 6, 2006 · Phosphoric acid diesters are, in general, exceedingly unreactive in water (1–3), so that the phosphodiester linkages that join the nucleotides of DNA are highly resistant to spontaneous hydrolysis.By extrapolation of earlier model experiments at elevated temperatures, the uncatalyzed hydrolysis of dimethyl phosphate in neutral solution was … WebThe mechanism of topoisomerase action includes the transient formation of an ester bond between a tyrosine residue of the enzyme and the DNA molecule. Later on, the breaks are …
