    Abstract: Polymers are provided comprising protein polymers comprising blocks of repeating units and sequences comprising amino acids, individually or in defined sequences, capable of enzyme catalyzed covalent bond formation for cross-linking, as exemplified by glutamine and/or lysine reactive for FXIII catalyzed isopeptide formation or non-amino acid polymers having side chains comprising such amino acids or sequences, which may be used for preparation of articles of manufacture, particularly cross-linkable compositions. By appropriate choice of the polymer, resorbable implantable polymers may be used in internal applications for mammals as formed objects or depots.

  • Patent number: 5763583
    Abstract: A process for the production of a solubilized protein is disclosed, which is obtained by reducing disulfide bonds in a disulfide bond-containing water-insoluble protein material into mercapto groups and subsequently converting a part or an entire portion thereof into carboxymethyldisulfide groups. In particular, the disclosed process for the production of a solubilized protein which comprises (a) treating a disulfide bond-containing water-insoluble protein material with an aqueous alkaline solution of a reducing agent, and (b) reacting the protein treated by step (a) with thioglycolic acid in the presence of an oxidizing agent under a weakly acidic to a weakly alkaline condition. A process for the production of regenerated protein products, which comprises regenerating disulfide bonds in the solubilized protein, is also disclosed.

  • Patent number: 5760004
    Abstract: Highly repetitive proteins which are relatively insoluble in water are chemically modified to increase solubility. The protein is reacted with a functionalizing agent to introduce additional polar functionalities and disrupt the order of the protein. The solubility of the protein in water is increased by the chemical modification, while adhesive and surfactant properties are retained.

  • Patent number: 5756677
    Abstract: cDNA clones encoding minor ampullate spidroin proteins (MiSP) are described. The translated amino acid sequence of the cloned cDNA shows that the MiSPs have a structure which exhibits an amino proximal nonrepetitive region, a repetitive portion and a carboxy-proximal nonrepetitive portion. The repetitive portion of the sequence is describable by a generic repeat formula. Comparison of the amino acid sequences derived from the translation with the sequences of short peptides obtained from solubilized minor ampullate spider silk suggests that the nonrepetitive portions of the protein are cleaved from the protein during secretion from the cells synthesizing the spidroins. This comparison also suggests that the minor ampullate spider silk is composed of at least three polypeptides.

  • Patent number: 5726040
    Abstract: A cosmetic composition including a non naturally-occurring extracellular matrix protein in combination with a cosmetic carrier is described. The protein is preferably of human origin and has not been previously cross-linked. The protein is most preferably selected from the group consisting of soluble human procollagen and soluble human tropoelastin. The protein may include at least one additional non-naturally occurring amino acid sequence moiety, the amino acid sequence moiety selected from the group consisting of a hydrophobic sequence, a hydrophilic sequence, and a lysine-rich sequence.A cosmetic composition in which the non naturally-occurring extracellular matrix protein is an isomorphic form of the protein is also described. The isomorph of the protein is preferably selected from the group consisting of elastin isomorphs, collagen isomorphs and fibronectin isomorphs. Most preferably, the isomorphs are of human origin and have not been previously cross-linked.
