The Topochemical Basis for Morphiceptin and Dermorphin Bioactivity, (9999)

Yamazaki, Toshimasa, Ro, Seonggu, Goodman, Murray

Morphiceptin (Tyr1-Pro2-Phe3-Phe4-NH2) and dermorphin (Tyr1-D-Ala2-Phe3-Gly4-Tyr5-Pro6-Ser7-NH2) are highly microns-receptor selective peptide opioids. Since the biologically important Tyr1 and Phe3...

Accurate automated clustering of two-dimensional data for single-nucleotide polymorphism genotyping by a combination of clustering methods: evaluation by large-scale real data (2007)

Takitoh, Shuichi, Fujii, Shogo, Mase, Yoichi, Takasaki, Junichi, Yamazaki, Toshimasa, Ohnishi, Yozo, ...

Motivation: The Invader assay is a fluorescence-based high-throughput genotyping technology. If the output data from the Invader assay were classified automatically, then genotypes for individuals...

The linker histone homolog Hho1p from Saccharomyces cerevisiae represents a winged helix-turn-helix fold as determined by NMR spectroscopy (2003)

Ono, Katsuki, Kusano, Osamu, Shimotakahara, Sakurako, Shimizu, Mitsuhiro, Yamazaki, Toshimasa, Shindo, Heisaburo

Hho1p is assumed to serve as a linker histone in Saccharomyces cerevisiae and, notably, it possesses two putative globular domains, designated HD1 (residues 41–118) and HD2 (residues 171–252),...

The guanosine binding mechanism of the Tetrahymena group I intron (1999)

Kitamura, Aya, Muto, Yutaka, Watanabe, Satoru, Kim, Insil, Ito, Takuhiro, Nishiya, Yoichi, ...

The Tetrahymena group I intron catalyzes self-splicing through two consecutive transesterification reactions, using a single guanosine-binding site (GBS). In this study, we constructed a model RNA...

Molecular Structure of the GARP Family of Plant Myb-Related DNA Binding Motifs of the Arabidopsis Response Regulators

Hosoda, Kazuo, Imamura, Aya, Katoh, Etsuko, Hatta, Tomohisa, Tachiki, Mari, Yamada, Hisami, ...

The B motif is a signature of type-B response regulators (ARRs) involved in His-to-Asp phosphorelay signal transduction systems in Arabidopsis. Homologous motifs occur widely in the GARP family of...

Solution structure of an RNA fragment with the P7/P9.0 region and the 3'-terminal guanosine of the tetrahymena group I intron.

Kitamura, Aya, Muto, Yutaka, Watanabe, Satoru, Kim, Insil, Ito, Takuhiro, Nishiya, Yoichi, ...

In the second step of the two consecutive transesterifications of the self-splicing reaction of the group I intron, the conserved guanosine at the 3' terminus of the intron (omegaG) binds to the...

A solution NMR study of the binding kinetics and the internal dynamics of an HIV-1 protease-substrate complex

Katoh, Etsuko, Louis, John M., Yamazaki, Toshimasa, Gronenborn, Angela M., Torchia, Dennis A., Ishima, Rieko

NMR studies of the binding of a substrate to an inactive HIV-1 protease construct, containing an active site mutation PRD25N, are reported. Substrate titration measurements monitored by HSQC spectra...
