Interstrand vs intrastrand crosslink
WebDec 19, 2024 · One possible explanation is the formation of long-range intra- or interstrand crosslinks between two nucleobases that are distant in the DNA primary structure but are spatially close to each other. 1,3-GNG intrastrand crosslinks (where G = guanine, N = adenine, cytosine, or thymine) can be formed in the reaction between transplatin and … WebMar 1, 1997 · Molecular dynamic simulations provided a structural explanation for this difference, in that the monofunctionally bound intermediates of mechlorethamine and phosphoramide mustard assumed thermodynamically stable conformations with the second arm in a position appropriate for intrastrand crosslink formation, while the …
