  • Publication number: 20090319234
    Abstract: This invention fragments ions ionized by an electro-spray ionization method or the like for a target protein whose three-dimensional structure is to be predicted, to fragment ions by a hexapole CID method or the like, and measures a fragmentation spectrum. The present invention determines fragment ion assignment information on an amino acid sequence of the target protein based on the measured fragmentation spectrum. The present invention specifies a region of the amino acid sequence of the target protein in which region the ions are dissociated to the fragment ions according to the determined fragment ion assignment information, and determines easily cleavable domain information on the amino acid sequence of the target protein according to the specified region. The present invention predicts the three-dimensional structure of the target protein.

  • Patent number: 7553650
    Abstract: The present invention relates to a method for designing and preparing mutant transglutaminases on the basis of the three-dimensional structure of MTG derived from Streptoverticillium mobaraense (MTG), and the mutant MTG thus prepared. The present invention provides a method for modifying MTG on the basis of the three-dimensional structure, and transglutaminase having reactivity on the substrate improved by the method. In the present invention, the binding site of MTG for the substrate is extrapolated based on the three-dimensional structure obtained by X-ray crystal structure analysis of MTG crystals, and the mutant transglutaminases are designed and produced by replacing, inserting or deleting amino acid residues positioned at the substrate-binding site of the transglutaminase.

  • Patent number: 6077814
    Abstract: A 1-phenyl, naphthyl or aralkyl-4-(N,N-di-substituted carbamoyl)-1,2,4-triazol-5-one derivative represented by the general formula (I) ##STR1## wherein A is an unsubstituted or substituted phenyl group, 1-naphthyl group, 5,6,7,8-tetrahydro-1-naphthyl group or an aralkyl group such as an unsubstituted or substituted benzyl group and so on, R.sub.1 is a lower alkyl group and so on, and R.sub.2 is an unsubstituted or substituted phenyl group and so on, was prepared as novel compounds. This 1-substituted-4-carbamoyl-1,2,4-triazol-5-one derivative does not substantially exhibit phytotoxicity to various agricultural crop plants and therefore is useful as a selective herbicide.
