    High-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 ...
  • 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 obert
    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 ...
