    • Satellites in the prokaryote world 

      Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2019-09-18)
      Article
      Accés obert
      Background Satellites or tandem repeats are very abundant in many eukaryotic genomes. Occasionally they have been reported to be present in some prokaryotes, but to our knowledge there is no general comparative study ...

    • Tandem repeats in Bacillus: Unique features and taxonomic distribution 

      Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2021-05-20)
      Article
      Accés obert
      Little is known about DNA tandem repeats across prokaryotes. We have recently described an enigmatic group of tandem repeats in bacterial genomes with a constant repeat size but variable sequence. These findings strongly ...

    • 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 obert
      We 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 ...

    • Unique features of satellite DNA transcription in different tissues of Caenorhabditis elegans 

      Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2023-02-03)
      Article
      Accés obert
      A large part of the genome is known to be transcribed as non-coding DNA including some tandem repeats (satellites) such as telomeric/centromeric satellites in different species. However, there has been no detailed study ...

    • Unique features of tandem repeats in bacteria 

      Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2020-08-24)
      Article
      Accés restringit per política de l'editorial
      DNA tandem repeats, or satellites, are well described in eukaryotic species, but little is known about their prevalence across prokaryotes. Here, we performed the most complete characterization to date of satellites in ...

    • Visualization of sequence and structural features of genomes and chromosome fragments. Application to CpG islands, Alu sequences and whole genomes 

      Subirana Torrent, Juan A.; Anokian, Ezequiel (2011-03-01)
      Article
      Accés restringit per política de l'editorial
      A very simple new program is presented (G-SQUARES). It is useful in order to visualize the composition and basic structural features of whole genomes and selected chromosome regions. The frequency of all dimer and tetramer ...
