Abstract: A task is to provide a fire-resistant fabric and a seat each having excellent flame retardancy, fire resistance, strength, comfortability, and formability, and a solution to problem is that a fire-resistant fabric which has a bending resistance of 95 mm or less in the warp direction or in the weft direction, as measured by the method prescribed in JIS L 1096 (2010) A method (45° cantilever method), is obtained using a flame-retardant fiber having an LOI of 26 or more, as measured in accordance with JIS L 1091 (1999) E-2 method.

Abstract: An object of the present invention is to provide a co-crystal of a Ras polypeptide which adopts a conformation having a pocket on the molecular surface of Ras and GTP or a GTP analog, a production method for the crystal, and a screening method for a Ras function inhibitor based on information about the conformation obtained by X-ray crystallographic analysis using the crystal. The object is achieved by focusing on a mutation which adopts a conformation having a pocket on the molecular surface of Ras, acquiring a mutant Ras polypeptide having introduced therein such mutation, producing a co-crystal of the mutant Ras polypeptide and a GTP analog, and further subjecting the co-crystal to X-ray crystallographic analysis to acquire structural information about the conformation including information about the structure surrounding the pocket.

Abstract: A peptide nanofiber having conductivity is provided. A conductive peptide nanofiber which includes a nanofiber formed through a manner of self-assembly of a peptide that has a nanofiber-forming ability and consists of an amino acid sequence of Xaa-Phe-Ile-Val-Ile-Phe-Xaa (SEQ ID NO: 1, wherein N-terminal Xaa is an arbitrary amino acid residue Xaa1; C-terminal Xaa is an arbitrary amino acid residue Xaa2; and Xaa1 and Xaa2 are an amino acid having an acidic side chain, an amino acid having a basic side chain, or an amino acid having a side chain with polarity according as acidity and basicity) or a derivative of the peptide and a conductive substance added thereto, the aforementioned conductive substance being added to an amino group of the peptide or the derivative.
