    摘要: Water-forming NADH oxidase derived from Streptococcus mutans should be further improved in terms of stability for practical use in industrial production. An object of the present invention is to provide an enzyme that is obtained through modification of a water-forming NADH oxidase, which is useful as an NAD+ regeneration system for stereoselective oxidation catalyzed by an oxidoreductase, by protein engineering techniques so that the enzyme can withstand long-term use without exhibiting a reduction of its activity for the regeneration of NAD+, that is, an enzyme having improved stability, and to provide a method for efficiently producing a useful substance such as an optically active alcohol or amino acid. The present invention relates to an enzyme modification method that can improve the stability of water-forming NADH oxidase derived from Streptococcus mutans by appropriately introducing mutation.

    摘要: A pair of compression rollers 38a and 38b parallel with each other are provided and powder grains are supplied to a powder grain introduction/compression part 50 formed between the rollers 38a and 38b and, thereby, compression moldings of the powder grains are formed. A powder grain press/feed means 20 is provided in a front stage of the rollers 38a and 38b. The press/feed means 20 has a deaerating barrel 24 and previously presses the powder grains supplied between the rollers 38a and 38b. In side surfaces of the rollers 38a and 38b, side seals 37 are arranged with clearances 72 maintained from the rollers 38a and 38b. During pressing the powder moldings, the powder grains enter into the clearances so that closer layers are formed between the side surfaces of the compression rollers 38a and 38b and the side seals 37, thereby sealing the powder grain introduction/compression part 50. In a rear stage of the rollers 38a and 38b, a shearing device 75 is provided and shears the compression moldings formed by the rollers 38a and 38b. Torque of the shearing device 75 is detected by a torque sensor, and the compression rollers 38a and 38b and the powder grain transport means 17 are controlled in accordance with the detected torque.

    摘要: Power steering apparatus for a vehicle comprising a rack rod operatively connected to a steering wheel and supported in a steering gear casing, the rack rod being drivable by a power cylinder consisting of an outer cylinder fixed to the steering gear casing, an inner cylinder disposed in the outer cylinder and fitted into the steering gear casing, and a piston mounted on the rack rod to divide the interior of the inner cylinder into first and second oil chambers. A control valve is mounted on the lower surface of the steering gear casing for controlling the operation of the power cylinder. The second oil chamber is in communication with the outer cylinder via the spaces between the coils of a coil spring, the inner cylinder being supported in floating state on the outer cylinder by the coil spring. A pair of parallel, annular or semi-annular oil passages are provided in that portion of the steering gear casing which is engaged with the inner cylinder. The oil passages are respectively in communication with a pair of output ports of the control valve. The oil passages are also in communication at respective upper portions thereof with the outer cylinder and the first oil chamber separately. Due to these internally provided oil passages, the number of parts and assembly steps of the apparatus can be minimized. Because the inner cylinder is supported in floating state by the coil spring on the outer cylinder, it can be kept concentric therewith so that the piston can be operated smoothly at all times. The mounting of the control valve under the gear casing leaves a large space above the gear casing for the installation of the engine.

    摘要: The present invention provides a method enabling convenient production of an optically active secondary alcohol useful as a pharmaceutical intermediate, particularly an optically active 1,2-diol and an optically active 2-alkanol, from an enantiomer mixture thereof. An oxidizing enzyme source having the capability of selectively oxidizing one enantiomer of secondary alcohol is allowed to act on an enantiomer mixture of secondary alcohol in the presence of a reducing enzyme source having the capability of reverse enantio-selectively reducing a ketone derivative, to convert the enantiomer mixture into a substantially single enantiomer at a theoretical percent recovery of 100%, whereby an optically active secondary alcohol is produced.
