摘要:
The present invention provides a recombinant plasmid comprising combining a hybrid plasmid vector with the isolated DNA sequences of one or more genes encoding nitrile degrading enzymes which are derived from bacteria belonging to the genus Rhodococcus, said hybrid plasmid vector comprising an isolated DNA sequence which confers on the vector the ability to replicate and amplify in the cells of bacteria belonging to the genus Rhodococcus, and an isolated DNA sequence which confers on the vector the ability to replicate and amplify in the cells of bacteria belonging to Escherichia coli, and an isolated DNA sequence containing a drug resistance gene.
摘要:
The present invention has disclosed the amino acid sequence and nucleotide sequence of the .alpha.- and .beta.-subunits of two types of nitrile hydratase derived from Rhodococcus rhodochrous J-1. The DNA fragment encoding nitrile hydratase is inserted into an expression vector and the recombinant vector is used for transformation. The transformant contains multiple copies of the gene and can produce much higher level of nitrile hydratase compared with conventionally used microorganisms.
摘要:
The present invention relates to a gene derived from Pseudomonas chlororaphis B23 strain which encodes a polypeptide having nitrile hydratase activity being capable of hydrating nitriles to amides. The invention also relates to a recombinant DNA containing the gene, and a transformant transformed with the recombinant DNA. The present invention further relates to a method of producing nitrile hydratase using the transformant and of amides using nitrile hydratase.

摘要:
A display processing device for displaying a display object in a display window and changing a display range includes a sectioning unit that divides the display window into a plurality of sections (screens) by creating boundary lines. Maps of geographical ranges to be displayed are sectioned and displayed in the plurality of screens. In the event that a boundary line is moved through a user input, the geographical ranges of the maps in the screens for which the screen size has become larger than an initial screen size are enlarged, and the maps in the screens which have become smaller than the initial screen size are reduced in scale in accordance with the reduction in screen size, while maintaining the geographical range of the maps displayed in the display window prior to the boundary line being moved.
