Abstract: The present invention relates to a novel human epidermal growth factor (hEGF)-trigger factor (TF) fusion protein and a use thereof. More particularly, the human epidermal growth factor (hEGF)-trigger factor (TF) fusion protein of the present invention has fused therein: a signal peptide of a Bacillus subtilis-derived xylanase; a human epidermal growth factor (hEGF); and an Escherichia coli-derived trigger factor (TF). Therefore, the present invention not only enhances the water solubility and expression rate of a target protein, but also notably enhances useful effects such as the effects of increasing skin cell growth and healing a wound, and thus may be widely used in various industries as an active ingredient for a functional cosmetic composition and a pharmaceutical composition.

Abstract: The present invention relates to an Fe—S fusion protein acting as an electron transport chain, a novel carbon monoxide:formate oxidoreductase (CFOR) including the Fe—S fusion protein, novel Thermococcus strain BCF12 transformed with CFOR, and the use thereof. According to the present invention, two different enzymes may be physically linked directly to each other through the Fe—S fusion protein of the present invention, and thus electrons generated from any one enzyme may be transported directly to another enzyme through the Fe—S cluster of the Fe—S fusion protein. Accordingly, a reaction that produces a target substance with high efficiency by directly supplying electrons necessary for the production of the target substance is possible without leakage of electrons generated in any one enzyme. In addition, the present invention has an advantage in that the overall enzyme reaction rate and yield can be dramatically improved using a new electron transport reaction. Furthermore, it is possible to ensure the stability of each enzyme by allowing the enzymes to exist in a physically fixed state in cells.

Abstract: This application relates to a cement mortar composition reinforced with a shredded waste fishing net and a method of manufacturing the cement mortar composition. In one aspect, the cement mortar composition includes cement mortar including cement, fine aggregate, and water and 0.5 to 2.0 parts by weight of a fibrous reinforcing material based on 100 parts by weight of the cement mortar. The fibrous reinforcing material may be manufactured by shredding a knotless fishing net and being formed of a single yarn that has a length of 3 mm to 60 mm and a diameter of 0.1 mm to 1 mm. The cement mortar composition that has improved crack resistance and tensile strength and in which an environmentally friendly and inexpensive reinforcing material obtained by shredding a waste fishing net at a random length instead of existing highly-expensive reinforcing material is included may be realized.
