Provided is a compound semiconductor nanoparticle that exhibits circularly polarized luminescence characteristics. CdS prepared inside a core of ferritin, which is a cage-like protein, exhibits a high circularly polarized luminescence (CPL). A wavelength of the circularly polarized luminescence (CPL) can be controlled by laser irradiation, thereby enabling utilization of the compound semiconductor nanoparticle in the field of bionanotechnology, for example, in creating a WORM (Write-Once Read-Many times) memory. As the cage-like protein, which is a protein with a cavity formed therein, a protein belonging to the ferritin protein family, such as apoferritin, or a recombinant thereof can be used.

A bacterial toxin protein such as a Shiga toxin protein is efficiently produced using plant cells. The plant cells are transformed using a DNA construct containing DNA encoding a hybrid protein in which the bacterial toxin proteins such as the Shiga toxin proteins are tandemly linked through a peptide having the following characteristics (A) and (B) to produce the bacterial toxin protein in the plant cells: (A) a number of amino acids is 12 to 30; and (B) a content of proline is 20 to 35%.

Provided is a crystal of a florigen activation complex, including a florigen, a 14-3-3 protein, and a bZIP transcription factor bound to each other. In addition, flowering of a plant is regulated by controlling mechanisms of interactions among those proteins utilizing the crystal. These are achieved as follows. With attention focused on the fact that Hd3a is bound to FD1 via GF14c to form a florigen activation complex, a crystal of the florigen activation complex is produced, conformational information is obtained through the use of the crystal of the florigen activation complex, and the flowering of a plant is regulated by controlling mechanisms of interactions among the florigen and the like utilizing such conformational information.
摘要:
Disclosed are an SiC semiconductor element and manufacturing method for an SiC semiconductor element in which the interface state density of the interface of the insulating film and the SiC is reduced, and channel mobility is improved. Phosphorus (30) is added to an insulating film (20) formed on an SiC semiconductor (10) substrate in a semiconductor element. The addition of phosphorous to the insulating film makes it possible to significantly reduce the defects (interface state density) in the interface (21) of the insulating film and the SiC, and to dramatically improve the channel mobility when compared with conventional SiC semiconductor elements. The addition of phosphorus to the insulating film is carried out by heat treatment. The use of heat treatment to add phosphorous to the insulating film makes it possible to maintain the reliability of the insulating film, and to avoid variation in channel mobility and threshold voltage.
摘要:
Analysis is made comprehensively on gene-disrupted strains derived from Bacillus subtilis to discover a novel Bacillus subtilis mutant strain which is excellent in the ability of producing various enzymes. The Bacillus subtilis mutant strain has a genomic structure having the deletion of any one of the regions shown in the deleted region list. The Bacillus subtilis mutant strain shows a significantly improved ability of secreting and producing a desired secreted protein when a gene encoding the protein is expressably introduced into the strain, compared to a case where the gene is introduced into a wild-type strain.
