Dynamic structures of Bacillus subtilis RecN–DNA complexes (2008)
Sánchez, Humberto, Cárdenas, Paula P., Yoshimura, Shige H., Takeyasu, Kunio, Alonso, Juan Carlos
Genetic and cytological evidences suggest that Bacillus subtilis RecN acts prior to and after endprocessing of DNA double-strand ends via homologous recombination, appears to participate in the...

Phase Transition in Reconstituted Chromatin (2004)
Nakai, Tonau, Hizume, Kohji, Yoshimura, Shige. H., Takeyasu, Kunio, Yoshikawa, Kenichi
By observing reconstituted chromatin by fluorescence microscopy (FM) and atomic force microscopy (AFM), we found that the density of nucleosomes exhibits a bimodal profile, i.e., there is a large...

A small container of several to a few hundred µm3 (i.e. bacterial cells and eukaryotic nuclei) contains extremely long genomic DNA (i.e. mm and m long, respectively) in a highly organized fashion....
Yoshimura, Shige H., Kim, Joongbaek, Takeyasu, Kunio
The proper function of the genome largely depends on the higher‐order architecture of the chromosome. To understand the detailed chromosome structure in a native state, we developed an...
Histone Core Slips along DNA and Prefers Positioning at the Chain End (2001)

Atomic force microscopy proposes a 'kiss and pull' mechanism for enhancer function (2000)
Yoshimura, Shige H., Yoshida, Chikashi, Igarashi, Kazuhiko, Takeyasu, Kunio
The DNase I-hyper-sensitive sites (HS2–HS4) in the β-globin gene enhancer region (locus control region; LCR) have been known as the target of Bachl/MafK heterodimers. We have demonstrated...
Hohmura, Ken I., Itokazu, Yutakatti, Yoshimura, Shige H., Mizuguchi, Gaku, Masamura, Yu-suke, Takeyasu, Kunio, ...
Among many scanning probe microscopies, atomic force microscopy (AFM) is a useful technique to analyse the structure of biological materials because of its applicability to non-conductors in...

Fast-scanning atomic force microscopy reveals the ATP/ADP-dependent conformational changes of GroEL
Yokokawa, Masatoshi, Wada, Chieko, Ando, Toshio, Sakai, Nobuaki, Yagi, Akira, Yoshimura, Shige H, ...
In order to fold non-native proteins, chaperonin GroEL undergoes numerous conformational changes and GroES binding in the ATP-dependent reaction cycle. We constructed the real-time...
