摘要：
A QM-MM calculation was carried out to study the mechanism of DNA cleavage by the dipeptide seryl-histidine (SH). The effective molecular recognition between SH and DNA through multi-hydrogen-bonds was obtained, as well as the corresponding structural parameters. The results could be used to explain the mechanism of DNA cleavage by SH, which supposed that the formation of penta-coordinate phosphorus intermediate caused the phosphodiester bond hydrolysis.
