Abstract: The present invention relates to a microorganism with increased carbon monoxide availability and use thereof.

Abstract: The present invention relates to a protein variant, a microorganism with enhanced carbon monoxide (CO) availability comprising the variant, and a use thereof.

Abstract: Provided is a method of producing a novel microorganism having a minimal genome. In particular, provided are a method of producing a novel microorganism having a smaller genome size than a wild-type, the method including the step of culturing the microorganism in a medium containing LB broth with stepwise decreasing concentrations of the LB broth; and a novel microorganism having a smaller genome size than a wild-type, produced by the above method. Despite the small genome size, the novel microorganism of the present disclosure may have a high growth rate, pyruvate production capacity, and protein translation efficiency thereby being usefully applied to industry such as production of recombinant proteins or pyruvate.

Abstract: A porous structure according to one embodiment of the present invention is constituted by a frame having a plurality of pores interconnected 3-dimensionally through a plurality of connecting passages. The plurality of pores defined by the frame are distributed in a closest packed state and are interconnected 3-dimensionally through a plurality of connecting passages in a symmetric structure, thus being effective in achieving a maximum porosity of the porous structure. A porous hierarchical structure according to one embodiment of the present invention includes a first porous structure having a plurality of 3-dimensionally interconnected first pores and a second porous structure having a plurality of 3-dimensionally interconnected second pores whose diameter is different from that of the first pores and surrounding and bonded to the first porous structure.

Abstract: Although metabolic networks have been reconstructed on a genome-scale, the corresponding reconstruction and integration of governing transcriptional regulatory networks has not been fully achieved. Here such an integrated network was constructed for amino acid metabolism in Escherichia coli. Analysis of ChlP-chip and gene expression data for the transcription factors ArgR, Lrp, and TrpR showed that 19/20 amino acid biosynthetic pathways are either directly or indirectly controlled by these regulators. Classifying the regulated genes into three functional categories of transport, biosynthesis, and metabolism leads to elucidation of regulatory motifs constituting the integrated network's basic building blocks. The regulatory logic of these motifs was determined based on the relationships between transcription factor binding and changes in transcript levels in response to exogenous amino acids. Remarkably, the resulting logic shows how amino acids are differentiated as signaling and nutrient molecules.

Abstract: The present invention provides a method of determining bacterial metastructure by integrating multiple genome-scale information yielded by high-throughput technologies. The metastructure constructs a universal metabolic engineering platform enabling a rational design of bacterial strains through optimization of gene and protein expression.

Abstract: A seat moving track assembly comprising a stationary rail having at a lower part of one side thereof recesses and having at an upper part of the other side thereof openings, a moving rail having first side holes to correspond to the recesses and second side holes to correspond to the openings, a locking member having first stopping protrusions projecting through the first side holes coupled into the recesses and second stopping protrusions projecting through second side holes coupled into the openings, an elastic connecting member having a shaft supporting part to rotatably support the locking member, an elastic pressing part to rotate the locking member, and unlocking means for rotating the locking member in the other direction to release a coupling between the first stopping protrusions and the recesses and a coupling between the second stopping protrusion and the openings, thereby providing stability and a simplified configuration.

Abstract: Disclosed is an asynchronous MAC based sensor node using a Wake-Up RF. The sensor node includes a main transceiver to transmit/receive data, a Wake-Up transceiver to transit a state of the sensor node; and a micro-control unit, which transmits a Wake-Up frame to at least one receiving node through the Wake-Up transceiver such that the receiving node is activated from an inactive state into an active state and transmits data to the activated receiving node through the main transceiver.

Abstract: The present invention relates to an apparatus for removing an eggshell, which provides a body and handle for holding an egg softly by linkage between them, a removing plate for breaking the eggshell with the handle, an operating device for expanding the removing plate so as to extract the contents in the egg so that the convenience in removing the eggshell is proposed, the eggshells are removed easily and rapidly, and most of all, the sanitation in removing the eggshell is improved.

Abstract: The present invention relates to an ashtray which could be used as the decoration due to good appearance as well as could not make other people unpleasant by covering the interior thereof, as it is not in use, and could cause ashes to be knocked off easily by the simple operation of the button as it is in use.
