    摘要: The present invention provides a method for producing L-fuculose and L-fucose which is suitable as an industrial method. L-Fuculose is synthesized from L-fucitol in the presence of a microorganism-derived protein having a dehydrogenase activity which results in production of L-fuculose from L-fucitol. The reaction system preferably contains NADH oxidase. L-Fuculose thus synthesized is then converted into L-fucose.

    摘要: The present invention provides a method of producing optically active amino acids from 5-substituted hydantoin by isolating a hydantoinase gene and an N-carbamyl-L-amino acid hydrolase gene involved in an ability to convert 5-substituted hydantoin or N-carbamylamino acid into optically active amino acids from a microorganism of the genus Microbacterium having the above ability and by improving gene amplification and transcriptional and translational activities thereby preparing a recombinant wherein the amount of the desired enzymes produced is increased. The hydantoinase gene is, for example, a DNA encoding for a protein having a hydantoinase activity, which has the nucleotide sequence set forth in SEQ ID NO:1 in the Sequence. The N-carbamyl-L-amino acid hydrolase gene is, for example, a DNA encoding for a protein having an N-carbamyl-L-amino acid hydrolase activity, which has the nucleotide sequence set forth in SEQ ID NO:3 in the Sequence.

    摘要: A semiconductor memory has at least a pair of bit lines, a plurality of word lines crossing the pair of bit lines, a pair of dummy word lines crossing the pair of bit lines, memory cells arranged at intersections between the bit lines and the word lines, dummy cells arranged at intersections between any the bit lines and the dummy word lines, a sense amplifier connected to the pair of bit lines, and a means for equalizing the potentials of the pair of bit lines. Each of the memory cell has a transistor and a capacitor. Each dummy cell has the same construction as each memory cell. The pair of bit lines and dummy cell capacitors are electrically connected at a predetermined timing and are set at a third voltage, the corresponding dummy cell is disconnected from one of the bit line pair, to which a selected memory cell capacitor is connected. Subsequently, a voltage difference between voltages on the bit lines is detected.
