    摘要: A protein structure capable of selective interaction with an organic target is provided. The protein structure is a polymer comprising as a repeating structural unit a recombinant fusion protein that is capable of selective interaction with the organic target. The fusion protein is comprising the moieties B, REP and CT, and optionally NT. B is a non-spidroin moiety of more than 30 amino acid residues, which provides the capacity of selective interaction with the organic target. REP is a moiety of from 70 to 300 amino acid residues and is derived from the repetitive fragment of a spider silk protein. CT is a moiety of from 70 to 120 amino acid residues and is derived from the C-terminal fragment of a spider silk protein. NT is an optional moiety of from 100 to 160 amino acid residues and is derived from the N-terminal fragment of a spider silk protein. The fusion protein and protein structure thereof is useful as an affinity medium and a cell scaffold material.

    摘要: The invention provides an isolated major ampullate spidroin protein, which consists of from 150 to 420 amino acid residues and is defined by the formula KEP-CT. KEP is a repetitive, N-terminally derived protein fragment having from 80 to 300 amino acid residues. CT is a C-terminally derived protein fragment having from 70 to 120 amino acid residues. The invention further provides an isolated fusion protein consisting of a first protein fragment, which is a major ampullate spidroin protein, and a second protein fragment comprising a fusion partner and a cleavage agent recognition site. The first protein fragment is coupled via said cleavage agent recognition site to the fusion partner. The invention also provides a method of producing a major ampullate spidroin protein and polymers thereof.

    摘要: A method of producing polymers of an isolated spider silk protein involves providing a solution of said spider silk protein in a liquid medium at pH 6.4 or higher and/or an ion composition that prevents polymerisation of the spider silk protein. The properties of the liquid medium are adjusted to a pH of 6.3 or lower and an ion composition that allows polymerisation of the spider silk protein. The spider silk protein is allowed to form polymers in the liquid medium, and the resulting spider silk protein polymers are isolated from the liquid medium. The resulting polymers are useful as fibers, films, foams, nets or meshes.
