  • Patent number: 12221639
    Abstract: The present invention provides a novel allulose epimerase variant in which an amino acid residue present at a specific position of an amino acid sequence of wild-type D-allulose 3-epimerase derived from Flavonifractor plautii is substituted with another amino acid residue, and various uses thereof. The novel allulose epimerase variant according to the present invention has a higher conversion activity of fructose to allulose than that of the wild-type D-allulose 3-epimerase derived from Flavonifractor plautii or a D-allulose epimerase variant W29K/G216S/M234I, and has excellent thermal stability especially under high temperature conditions of 60° C. or higher, thereby preventing contamination during an industrial-scale enzymatic conversion reaction for the mass production of allulose, shortening the production time, and reducing the production costs.

  • Publication number: 20250042944
    Abstract: The present invention relates to squid-derived peptides and uses thereof and, more specifically, to uses of squid-derived peptides squidtocin and pro-sepiatocin for prevention or treatment of V1B receptor-related diseases. It has been confirmed that the squidtocin and pro-sepiatocin according to the present invention have an effect of inducing activation of a V1B receptor which is a type of vasopressin receptor. The V1B receptor which is a type of vasopressin receptor is present in the anterior pituitary and in the hippocampal CA2 region, and it is known that the V1B receptor increases intracellular calcium concentration and is involved in response to stress and sociality. Accordingly, the squidtocin and the pro-sepiatocin according to the present invention can be used in various ways in the field of prevention, amelioration, or treatment of V1B receptor-related diseases.
