An automatic procedure is proposed to identify, from the protein sequence database, conserved amino acid patterns (or sequence motifs) that are exclusive to a group of functionally related proteins. This procedure is applied to the PIR database and a dictionary of sequence motifs that relate to specific superfamilies constructed. The motifs have a practical(More)
Nucleotide sequence analysis of the cDNA and the genomic clones for rat DNA polymerase beta revealed the existence of a 1,005-base pair open reading frame capable of encoding a Mr = 38,269 polypeptide of 335 amino acid residues. The region of 174 amino acid residues between the 42nd and 215th residues of the DNA polymerase beta polypeptide has extensive(More)
This paper describes Japanese textual entailment recognition systems for NTCIR-10 RITE2. The tasks that we participated in are the Japanese BC subtask and the Ex-amBC subtask. Our methods are based on some machine learning techniques with surface level, syntax and semantic features. We use two ontologies, the Japanese WordNet and Nihongo-Goi-Taikei, and(More)
From protein sequence comparison data found in the literature, a library was organized using peptide fragment sequences which are common to related proteins. Each of the fragments was then examined for its occurrence in all the protein superfamilies defined by the NBRF-PIR data base. We have selected those fragment peptides that appear exclusively in one or(More)
