英文摘要 | Investigating the interaction between protein and stretched DNA molecules has become a new way to study the protein DNA interaction. The conformations from different stretching methods give us a further understanding of the interaction between protein and DNA. We study the conformational variations of a 22-mer DNA caused by stretching both 3'- and 5'-termini by molecular dynamics simulations. It requires 250 kJ/mol to stretch the DNA molecule by 3'5'-termini for 3.5 nm and the force plateau is at 123.8 pN. The stretching 3'5'-termini leads to large values of the angle opening and the dihedral propeller between bases in one base pair, the double helix untwists from 34 degrees to 20 degrees and the successive base pairs rolls to the side of the DNA major groove. The distances between successive base pairs increases from 3.2 angstrom to 5.6 angstrom. |
