Abstract: PURPOSE:To allow to massively and inexpensively secrete the subject pure substance in a medium by introducing a specific recombined DNA coding a chicken lysozyme signal peptide in a yeast and subsequently culturing the transformed yeast. CONSTITUTION:A yeast transformant holding a recombined DNA containing a yeast promoter and a hybrid pre-lysozyme gene comprising a region coding a chicken lysozyme signal peptide and a human lysozyme structure gene region is cultured. The transformant of the yeast is ordinarily prepared by synthesizing a DNA containing the hybrid pre-lysozyme gene and the yeast promoter, recombining the DNA with a manifestation vector and subsequently transforming a host, yeast, with the prepared recombined plasmid.

Abstract: PROBLEM TO BE SOLVED: To provide a hydrogen storage electrode having a high capacity and a high discharge rate by incorporating a specific element into a titanium - nickel alloy. SOLUTION: A hydrogen storage electrode comprises, as a constituent, a molding made of mixture powder including a titanium - nickel alloy containing oxygen. Although the titanium - nickel alloy containing oxygen is not particularly limited as long as oxygen (atoms) is incorporated into the Ti2 Ni alloy, it preferably has a composition expressed by a general formula: Ti4 Ni2 Ox (wherein 0.1

Abstract: PURPOSE:To produce a large amount of pure human lysozyme useful for medical treatment, inexpensively, by transforming a host yeast cell with a plasmid vector into which a specific synthetic human lysozyme is inserted and cultivating the prepared transformant. CONSTITUTION:A human lysozyme gene having a nucleotide sequence consisting of a nucleotide shown by the formula, obtained by chemical synthesis, is inserted into a given site (e.g., BamHI cleavage site) of a plasmid vector (e.g., pBR322) capable of multiplying in yeast cell and of transferring and translating the inserted gene, to form a recombinant plasmid (e.g., pHLY-1). Then, yeast is transformed with the recombinant plasmid to give a transformant [Saccharomyces cerevisiae KK4(YEpHYL-1)]. Then, this transformant is cultivated in a medium consisting of several amino acids, uracil, galactose to produce human lysozyme.

Abstract: PURPOSE:To provide a promoter useful for the expression of heterogenetic gene in a system containing yeast as a host, and having the region represented by a specific DNA base sequence to the upstream-side of the 5'-terminal in addition to the known base sequence region of a yeast enolase promoter. CONSTITUTION:The region expressed by the DNA base sequence of formula is linked to the upstream-side of 5'-terminal of a yeast enolase promoter in addition to the known base sequence region of the promoter. The obtained promoter has the expression activity of the gene managing the yeast enolase, and is useful for the expression of heterogenic gene in a system containing yeast as a host. The promoter contains the region corresponding to about 720 base pairs sited upstream from the enolase translation initiation codon.
