Wang-Landau molecular dynamics technique to search for low-energy conformational space of proteins (2007)

Nagasima, Takehiro, Kinjo, Akira R., Mitsui, Takashi, Nishikawa, Ken

Multicanonical molecular dynamics (MD) is a powerful technique for sampling conformations on rugged potential surfaces such as protein. However, it is notoriously difficult to estimate the...

Gene cluster analysis method reliably identifies horizontally transferred genes and reveals their involvement in operon formation (2006)

Homma, Keiichi, Fukuchi, Satoshi, Nakamura, Yoji, Gojobori, Takashi, Nishikawa, Ken

The formation mechanism of operons remains controversial despite the proposal of many models. Although acquisition of genes from other species, horizontal gene transfer, is considered to occur,...

CRNPRED: highly accurate prediction of one-dimensional protein structures by large-scale critical random networks (2006)

Kinjo, Akira R, Nishikawa, Ken

Abstract Background One-dimensional protein structures such as secondary structures or contact numbers are useful for three-dimensional structure prediction and helpful for intuitive understanding of...

Predicting Secondary Structures, Contact Numbers, and Residue-wise Contact Orders of Native Protein Structure from Amino Acid Sequence by Critical Random Networks (2005)

Kinjo, Akira R., Nishikawa, Ken

Prediction of one-dimensional protein structures such as secondary structures and contact numbers is useful for the three-dimensional structure prediction and important for the understanding of...

Predicting Residue-wise Contact Orders of Native Protein Structure from Amino Acid Sequence (2005)

Kinjo, Akira R., Nishikawa, Ken

Residue-wise contact order (RWCO) is a new kind of one-dimensional protein structures which represents the extent of long-range contacts. We have recently shown that a set of three types of...

Recoverable One-dimensional Encoding of Three-dimensional Protein Structures (2005)

Kinjo, Akira R., Nishikawa, Ken

Protein one-dimensional (1D) structures such as secondary structure and contact number provide intuitive pictures to understand how the native three-dimensional (3D) structure of a protein is encoded...

Genome Informatics 14: 468--469 (2003) Estimation of the Number of Orphan Genes in the (2004)

Satoshi Fukuchi, Ken Nishikawa

Introduction In annotations of genome sequences a considerable fraction of putative proteins are left without sequence similarity to known proteins. These genes or open reading frames (ORFs) have...

Integrative Annotation of 21,037 Human Genes Validated by Full-Length cDNA Clones (2004)

Tadashi Imanishi, Takeshi Itoh, Yutaka Suzuki, Claire O'Donovan, Satoshi Fukuchi, Kanako O. Koyanagi, ...

An international team has systematically validated and annotated just over 21,000 human genes using full-length cDNA, thereby providing a valuable new resource for the human genetics community.

Integrative Annotation of 21,037 Human Genes Validated by Full-Length cDNA Clones (2004)

Tadashi Imanishi, Takeshi Itoh, Yutaka Suzuki, Claire O'Donovan, Satoshi Fukuchi, Kanako O. Koyanagi, ...

The human genome sequence defines our inherent biological potential; the realization of the biology encoded therein requires knowledge of the function of each gene. Currently, our knowledge in this...

Nucleotide Sequence of a Gene Encodes Characteristic Features of an Organism as Well as an Amino Acid Sequence (1998)

Motonori Ota, Ken Nishikawa, Tatsuo Ooi

occus jannaschii, Archaeoglobus fulgidus, and Saccharomyces cerevisiae have been investigated [2]. The dinucleotide composition was significantly differentbetween the organisms. The distribution of...

Discrimination of Intracellular and Extracellular Proteins By Single Residue and Residue-Pair Scores (1995)

Ken Nishikawa

protein was excluded in the analysis. Membrane proteins were excluded from the analysis. We prepared two sets of sequence data, one was a training set to determine a parameter set of score and the...

GTOP: a database of protein structures predicted from genome sequences

Kawabata, Takeshi, Fukuchi, Satoshi, Homma, Keiichi, Ota, Motonori, Araki, Jiro, Ito, Takehiko, ...

Large-scale genome projects generate an unprecedented number of protein sequences, most of them are experimentally uncharacterized. Predicting the 3D structures of sequences provides important clues...
