Synthesis of a novel nucleotide unit containing cytosine analog bearing phosphodiester function and formation of silver(I)-mediated DNA duplex
Autor: A.T.M. Zafrul Azam, Itaru Okamoto, Akira Ono
Publikováno v: Nucleosides, nucleotidesnucleic acids. 41(11)
Novel modified cytosine analogs bearing phosphodiester/thiophosphodiester functionality were synthesized. The interactions between different metal ions and modified cytosine-cytosine base-pairs in DNA duplexes were investigated by UV-melting experime

Dye-Conjugated Spinach RNA by Genetic Alphabet Expansion
Autor: Kyung Hyun Lee, Michiko Kimoto, Gota Kawai, Itaru Okamoto, Andrea Fin, Ichiro Hirao
Light-emitting systems using an RNA aptamer-dye pair, such as Spinach RNA, are an attractive method for imaging and tracing RNA expression in vitro and in vivo. We present an alternative Spinach method by genetic alphabet expansion using an unnatural

Cognate base-pair selectivity of hydrophobic unnatural bases in DNA ligation by T4 DNA ligase
Autor: Hui Pen Tan, Si Hui Gabriella Soh, Itaru Okamoto, Ichiro Hirao, Michiko Kimoto
Publikováno v: Biopolymers
We present cognate base pair selectivity in template‐dependent ligation by T4 DNA ligase using a hydrophobic unnatural base pair (UBP), Ds‐Pa. T4 DNA ligase efficiently recognizes the Ds‐Pa pairing at the conjugation position, and Ds excludes t

High‐Resolution Crystal Structure of a Silver(I)–RNA Hybrid Duplex Containing Watson–Crick‐like CSilver(I)C Metallo‐Base Pairs
Autor: Yoshiyuki Tanaka, Takenori Dairaku, Jiro Kondo, Itaru Okamoto, Yoshinari Tada, Akira Ono, Hisao Saneyoshi
Publikováno v: Angewandte Chemie International Edition. 54:13323-13326
Metallo-base pairs have been extensively studied for applications in nucleic acid-based nanodevices and genetic code expansion. Metallo-base pairs composed of natural nucleobases are attractive because nanodevices containing natural metallo-base pair

Development of a photolabile protecting group for phosphodiesters in oligonucleotides
Autor: Hisao Saneyoshi, Akira Ono, Yuki Ando, Naoki Sagawa, Kanami Shimamura, Itaru Okamoto, Takahito Tomori
Publikováno v: Bioorganic & Medicinal Chemistry Letters. 25:2129-2132
A photolabile protecting group, consisting of an o-nitrobenzyl group and a 3-(2'-hydroxy-3',6'-dimethylphenyl)-2,2-dimethylpropyl moiety, was developed for phosphodiesters in oligodeoxyribonucleotides. Deprotection was triggered by photoirradiation a

Crystal Structure of Metallo DNA Duplex Containing Consecutive Watson-Crick-like T-HgII-T Base Pairs
Autor: Tom Yamada, Jiro Kondo, Akira Ono, Itaru Okamoto, Yoshiyuki Tanaka, Chika Hirose
Publikováno v: Angewandte Chemie International Edition. 53:2385-2388
The metallo DNA duplex containing mercury-mediated T-T base pairs is an attractive biomacromolecular nanomaterial which can be applied to nanodevices such as ion sensors. Reported herein is the first crystal structure of a B-form DNA duplex containin

Hg2+-Trapping Beads: Hg2+-Specific Recognition through Thymine–Hg(II)–Thymine Base Pairing
