WebApr 6, 2024 · Recently, it was reported that HMCES-crosslinks in ssDNA are also reversible . Interestingly, we found that HMCES-crosslinks are destabilised in dsDNA, with a half-life of approximately 3.5 hours at 30°C. This half-life is much shorter than that of the Q-GR adduct, suggesting that the de-crosslinking reaction is enzymatic.
