    摘要： Disclosed is a method for producing a protein fiber (36), the method including: bringing a spinning dope (6) containing a protein and an organic solvent into contact with a coagulation liquid (11) to coagulate the protein, wherein a content of the protein in the spinning dope (6) is more than 10% by mass based on a total amount of the spinning dope (6), and the coagulation liquid (11) contains water or an aqueous solution of pH 0.25 or more and pH 10.00 or less.

    摘要： The present invention relates to a modified fibroin including a domain sequence represented by Formula 1: [(A) n motif-REP] m or Formula 2: [(A) n motif-REP] m -(A) n motif, and having a serine residue content rate of less than 5.5%. [In Formula 1 and Formula 2, the (A) n motif represents an amino acid sequence consisting of 4 to 27 amino acid residues, and the number of alanine residues with respect to the total number of amino acid residues in the (A) n motif is 80% or more. REP represents an amino acid sequence consisting of 10 to 200 amino acid residues. m represents an integer of 10 to 300. The plurality of (A) n motifs may be the same amino acid sequence or different amino acid sequences. A plurality of REPs may be the same amino acid sequence or different amino acid sequences.]
