Imino proton NMR analysis of HDV ribozymes: nested double pseudoknot structure and Mg2+ ion-binding site close to the catalytic core in solution

Tanaka, Yoichiro, Hori, Tamaki, Tagaya, Mitsuhiro, Sakamoto, Taiichi, Kurihara, Yasuyuki, Katahira, Masato, ...

Minimized trans-acting HDV ribozyme systems consisting of three (Rz-3) and two (Rz-2) RNA strands were prepared and their folding conformations were analyzed by NMR spectroscopy. The guanosine...

Unfolding of quadruplex structure in the G-rich strand of the minisatellite repeat by the binding protein UP1

Fukuda, Hirokazu, Katahira, Masato, Tsuchiya, Naoto, Enokizono, Yoshiaki, Sugimura, Takashi, Nagao, Minako, ...

The mouse hypervariable minisatellite (MN) Pc-1 consists of tandem repeats of d(GGCAG) and flanked sequences. We have previously demonstrated that single-stranded d(GGCAG)n folds into the...

Method for direct discrimination of intra- and intermolecular hydrogen bonds, and characterization of the G(:A):G(:A):G(:A):G heptad, with scalar couplings across hydrogen bonds

Sotoya, Hidetsugu, Matsugami, Akimasa, Ikeda, Tetsuro, Ouhashi, Kiyoshi, Uesugi, Seiichi, Katahira, Masato

Discrimination of intra- and intermolecular hydrogen bonds in a symmetric multimer has not been accomplished yet, although such discrimination would provide a crucial basis for construction of the...

Human vault-associated non-coding RNAs bind to mitoxantrone, a chemotherapeutic compound

Gopinath, Subash C. B., Matsugami, Akimasa, Katahira, Masato, Kumar, Penmetcha K. R.

Human vaults are the largest cytoplasmic ribonucleoprotein and are overexpressed in cancer cells. Vaults reportedly function in the extrusion of xenobiotics from the nuclei of resistant cells, but...

Unexpected A-form formation of 4′-thioDNA in solution, revealed by NMR, and the implications as to the mechanism of nuclease resistance

Matsugami, Akimasa, Ohyama, Takako, Inada, Masashi, Inoue, Naonori, Minakawa, Noriaki, Matsuda, Akira, ...

Fully modified 4′-thioDNA, an oligonucleotide only comprising 2′-deoxy-4′-thionucleosides, exhibited resistance to an endonuclease, in addition to preferable hybridization with RNA. Therefore,...
