Document Type and Number:
Japanese Patent JP6995371
Kind Code:
B2
Abstract:
The present invention establishes a process for producing a protein using a chemical synthesis method, in particular, using both an enzymatic polymerization method and a block copolymerization method. Provided are: a protein produced by the process and having properties that are similar or superior to those of natural silk protein; and products produced from the protein, such as a resin, a fiber, and a film. The present invention provides: a protein comprising a poly(amino acid) formed from a single amino acid and/or a polypeptide formed from a plurality of amino acids, the protein being a block copolymer which comprises at least two kinds of blocks that each are the poly(amino acid) or the polypeptide, the at least two kinds differing in the kind of amino acid and/or in amino-acid makeup, the blocks having been repeatedly arranged by block copolymerization; and products produced from the protein.
