摘要:
The present invention provides a polypeptide comprising an amino acid sequence in which at least one amino acid is deleted, substituted or added in an amino acid sequence of isopropylmalate isomerase derived from a microorganism belonging to coryneform bacteria, wherein a coryneform bacterium which produces the polypeptide comprising the amino acid sequence as the sole isopropylmalate isomerase exhibits a partial leucine requirement in a minimal medium; a DNA encoding the polypeptide, a recombinant DNA comprising the DNA, a microorganism transformed with the recombinant DNA, and a process for producing an L-amino acid using the microorganism.
摘要:
The present invention relates to processes for producing compounds by using a protein derived from a microorganism belonging to the genus Bacillus, which has an activity of hydroxylating a compound represented by the formula (I-a): wherein R1 represents a hydrogen atom, a substituted or unsubstituted alkyl, or an alkali metal, and R2 represents a substituted or unsubstituted alkyl or substituted or unsubstituted aryl, or a ring-closed lactone from thereof.
摘要:
Novel polynucleotides derived from microorganisms belonging to coryneform bacteria and fragments thereof, polypeptides encoded by the polynucleotides and fragments thereof, polynucleotide arrays comprising the polynucleotides and fragments thereof, recording media in which the nucleotide sequences of the polynucleotide and fragments thereof have been recorded which are readable in a computer, and use of them.
摘要:
A data retrieval system capable of carrying out the retrieval using the secondary information of the primary data to be retrieved such as environmental information or structural information as the retrieval key. In the system, the primary data which are filing target to be stored and retrieved are stored in a first memory while secondary information associated with the primary data, which are not directly related with data content of the primary data, are stored in a second memory in correspondence to the primary data stored in the first memory. Then, when a retrieval key specifying a desired retrieval of the primary data from the first memory is entered, the secondary information is selected from the second memory in accordance with the retrieval key, and the primary data corresponding to the secondary information selected in accordance with the retrieval key is retrieved and outputted as a retrieval result.
摘要:
A multiplex transmission system includes a number of multiplex transmission devices connected to each other via a common transmission line for transmitting frames of data. Each frame of data includes a string of bits. The number of multiplex transmission devices includes a first multiplex transmission device having a first communication controller, the first communication controller transmitting a first frame of data at predetermined intervals of time while changing a predetermined bit of data in the first frame; and a second multiplex transmission device having a second communication controller, the second communication controller transmitting a second frame of data to the first multiplex transmission device in response to one of (i) a change in input data from an external equipment, and (ii) a change in the predetermined bit of the first frame when the first frame is received by the second multiplex transmission device from the first multiplex transmission device.
摘要:
A method and an apparatus for multi-window display with enhanced window manipulation facilities. In the apparatus, window images to be displayed in multi-window display are stored in a bit map memory. Various image processing operations are performed on the window images stored in the bit map memory, by regarding the window images as graphic images. Appropriate sections of processed window images are transferred to a frame buffer by using a bit block transfer device, and the image in the frame buffer is displayed on a display device.
