| + | The traditional Watson-Crick base pairs in DNA may occasionally adopt a Hoogsteen conformation, with a different organization of hydrogen bonds. Previous crystal structures have shown that the Hoogsteen conformation is favored in alternating AT sequences of DNA. Here we present new data for a different sequence, d(ATTAAT)2, which is also found in the Hoogsteen conformation. Thus we demonstrate that other all-AT sequences of DNA with a different sequence may be found in the Hoogsteen conformation. We conclude that any all-AT sequence might acquire this conformation under appropriate conditions. We also compare the detailed features of DNA in either the Hoogsteen or Watson-Crick conformations. | ||
