    • The present invention relates to novel mutated ornithine decarboxylase protein having enhanced capability of producing purtrescine, and to use thereof. According to the present invention, the mutated ornithine decarboxylase protein has putrescine conversion activity 21 times greater than that of natural type protein. When introduced into a prior putrescine-producing strain, the mutated ornithine decarboxylase protein significantly increases putrescine producing activity of the strain. Therefore, the mutated ornithine decarboxylase protein is an alternative for a protein used in the prior chemical synthesis pathway, and is expected to be used for more efficient mass-production of putrescine. In the mutated ornithine decarboxylase protein, a 163rd isoleucine amino acid residue and a 165th glutamic acid from an N-terminal of ornithine decarboxylase (ODC) having an amino acid sequence represented by SEQ ID: 1 are mutated.
    • 本发明涉及具有增强的产生purtresine的能力的新的突变鸟氨酸脱羧酶蛋白及其应用。 根据本发明,突变的鸟氨酸脱羧酶蛋白质具有比天然型蛋白质高21倍的腐胺转化活性。 当引入现有的腐胺生产菌株时,突变的鸟氨酸脱羧酶蛋白显着增加菌株的腐胺产生活性。 因此,突变的鸟氨酸脱羧酶蛋白是用于现有化学合成途径中的蛋白质的替代物,并且预期用于更有效地批量生产腐胺。 在突变的鸟氨酸脱羧酶蛋白中,具有SEQ ID:1所示氨基酸序列的鸟氨酸脱羧酶(ODC)N末端的第163位异亮氨酸氨基酸残基和第165位谷氨酸被突变。

    • PURPOSE: A transparent display apparatus is provided to selectively control transparency and visibility using a blind panel of cholesteric liquid crystal base. CONSTITUTION: An image display unit(10) displays an image using an element consisting of transparent material. A blind panel(20) is combined with the bottom of the image display unit. The blind panel transmits light of visible light band among lights radiated to the blind panel side or reflects the light to the image display side after passing through the image display unit. The blind panel comprises a CLC(Cholesteric Liquid Crystal) which is combined between a first transparent electrode for applying voltage and a transparent electrode more than one layer.
    • 目的:提供一种透明显示装置,以选择性地使用胆甾醇型液晶基板的盲板控制透明度和可视性。 构成:图像显示单元(10)使用由透明材料构成的元件显示图像。 盲板(20)与图像显示单元的底部组合。 盲板在照射到盲板侧的光之间透射可见光带的光,或者在通过图像显示单元之后将光反射到图像显示侧。 盲板包括CLC(胆固醇液晶),其组合在用于施加电压的第一透明电极和多于一层的透明电极之间。
