Structure of the DNA duplex d(ATTAAT)(2) with Hoogsteen hydrogen bonds
Acosta Reyes, Francisco Javier; Subirana, Juan Antonio; Campos López, Josefina de Lourdes; Alechaga, Elida (2015-03-17)
Article
Accés obertThe 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 ... -
The influence of Ni2+ and other ions on the trigonal structure of DNA
Acosta Reyes, Francisco Javier; Pagan, Mireia; Fonfría-Subirós, Elsa; Saperas Plana, Núria; Subirana Torrent, Juan A.; Campos López, Josefina de Lourdes (Wiley, 2021-04-13)
Article
Accés obertWe present a new structure of a DNA dodecamer obtained in the presence of Ni2+ ions. The DNA forms Ni-guanine cross-links between neighboring molecules. Our results show that an adequate dosage of Ni2+ may help to form ... -
Two high-mobility group box domains act together to underwind and kink DNA.
Sánchez Giraldo, Raquel; Acosta Reyes, Francisco Javier; Malarkey, Christopher S.; Saperas Plana, Núria; Churchill, Mair E. A.; Campos López, Josefina de Lourdes (2015-07-02)
Article
Accés obertHigh-mobility group protein 1 (HMGB1) is an essential and ubiquitous DNA architectural factor that influences a myriad of cellular processes. HMGB1 contains two DNA-binding domains, box A and box B, which have little ...
