Abstract: Provided is a method for treating a symptom of vibrio infection by using an RTX toxin production inhibitor comprising N-(4-oxo-4H-thieno[3,4-c]chromen-3-yl)-3-phenylprop-2-ynamide having derivatives thereof which can repress (prevent or treat) a symptom of vibrio infection by inhibiting RTX toxin production, other than directly killing vibrio bacteria, to not allow vibrio bacteria to have pathogenicity, and thereby can be an alternative to antibiotics that aim to kill bacteria themselves and thus fundamentally retain the problem of resistance incurrence.

Abstract: The present disclosure relates to a composition for promoting plant growth containing an YxaL protein and a method for mass-producing an YxaL protein. The YxaL protein may be expressed constitutively and in large amounts in a recombinant transformed cell line. When the YxaL protein is applied to seed soaking treatment, root development is improved, and the expression of plant genes involved in root growth is improved in favor of plant growth. Thus, the YxaL protein may be effectively used to promote plant growth.

Abstract: A grid sample production apparatus includes: a frame in which an internal space is formed; a grid unit which is vertically provided on an upper side of the frame, and grips a grid at a lower end; a filter unit which is provided to be movable inside the frame and selectively absorbs the protein liquid of the grid gripped at one end of the grid unit; a laser unit which is provided on one side of the filter unit; a screen unit which is disposed inside the frame and on which a diffraction image appears by the laser from the laser unit by being diffracted by the grid; and a liquid amount analysis unit which analyzes an illuminance of the diffraction image appeared on the screen unit and determines whether the protein liquid of the grid is disposed in an appropriate amount.

Abstract: The present invention relates to a thermostable enzyme with a 2.1 Å crystal structure of a propeller type comprising six external blades that encompass the outer boundary of the crystal and six internal calcium-binding sites that are embedded inside the above crystal. Each of the six blades comprises 4 or 5 anti-parallel &bgr;-strands, and the six calcium binding sites consist of 3 high-affinity calcium binding sites and 3 low-affinity binding sites, which are involved in the enzyme's thermostability and catalytic activity, respectively. The above-mentioned Ca2+ binding motifs are expected to be utilized in synthesizing highly thermostable proteins and the elucidation of active sites of an enzyme from a three-dimensional structure can help to design new enzymes having those sites with the aid of recent advanced technology of protein engineering.
