  • Patent number: 9187537
    Abstract: There are provided a recombinant silk protein derived from sea anemones, a method for producing the same, and a composition for preparing a silk fiber including same. The recombinant silk protein derived from sea anemones has sequence features similar to genetic information of a silk protein derived from spiders and silkworms. Also, a large amount of recombinant silk protein derived from sea anemones may be produced from a transformant and it has good physical properties such as strength and elasticity. Therefore, the recombinant silk protein derived from sea anemones can be usefully applied in various industrial fields in which natural silk protein can be applied, and it is expected to create new industrial fields based on its distinctive mechanical properties.

  • Patent number: 8673986
    Abstract: The present invention relates to a coacervate comprising a mussel adhesive protein and an anionic polymer, and more particularly, to a coacervate prepared by mixing a mussel adhesive protein with an anionic polymer, and a novel use thereof. In the present invention, a coacervate prepared by mixing a mussel adhesive protein and an anionic polymer shows a very excellent adhesive strength to various substrates such as cells or metals, and is able to maintain its adhesive strength in the presence of water or under water, thereby being effectively used as an adhesive. Moreover, it has an activity capable of encapsulating bioactive materials, thereby being effectively used as an active component of a composition for delivering bioactive materials.
