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...

NMR structures of double loops of an RNA aptamer against mammalian initiation factor 4A

Sakamoto, Taiichi, Oguro, Akihiro, Kawai, Gota, Ohtsu, Takashi, Nakamura, Yoshikazu

A high affinity RNA aptamer (APT58, 58 nt long) against mammalian initiation factor 4A (eIF4A) requires nearly its entire nucleotide sequence for efficient binding. Since splitting either APT58 or...

Solution structure and functional importance of a conserved RNA hairpin of eel LINE UnaL2

Nomura, Yusuke, Kajikawa, Masaki, Baba, Seiki, Nakazato, Shinta, Imai, Takayuki, Sakamoto, Taiichi, ...

The eel long interspersed element (LINE) UnaL2 and its partner short interspersed element (SINE) share a conserved 3′ tail that is critical for their retrotransposition. The predicted secondary...
