摘要:
An isolated hyperthermostable .beta.-galactosidase gene derived from Pyrococcus furiosus is described. Examples include DNA sequences shown in SEQ ID NO. 2 and SEQ ID NO. 4 and DNAs hybridizable with these DNAs. A method of cloning the hyperthermostable .beta.-galactosidase gene in which each of the above sequences or portions thereof is used as a probe or primer is described. A process for producing a hyperthermostable .beta.-galactosidase by culturing a transformant into which a plasmid containing each of the above genes has been introduced is described. A particularly preferred gene encodes an SDS-resistant hyperthermostable .beta.-galactosidase.

摘要:
This invention provides an antibody having antigen binding activity and which has a heavy chain constant region into which has been introduced an RGDS amino acid sequence giving the antibody affinity for cells, including macrophages. The antibody exhibits artificial cell adhesive activity which is the newly expressed activity that results from insertion of the RGDS amino acid sequence. This antibody having artificial cell adhesive activity can accelerate the phagocytosis of macrophages, and can activate other effector cells. Therefore, this antibody contributes to the self-defense mechanism.

摘要:
A nucleic acid comprising a transcription regulation sequence whose transcription is induced by a trans-acting factor of a human immunodeficiency virus and a gene encoding a polypeptide having an endoribonuclease activity specific to single-stranded RNA, wherein the gene is located in such a position that the expression of the gene can be regulated by the transcription regulation sequence; a method for production of a cell showing an inhibited replication of a human immunodeficiency virus therein, the method comprising the step of introducing the nucleic acid into a cell; and a method for treatment or prevention of a human immunodeficiency virus infection.
摘要:
The present invention provides a fungal bed culture of a hon-shimeji mushroom inoculated with a liquid seed culture wherein the surface of a culture medium for cultivation has a liquid seed culture inoculated portion and a liquid seed culture non-inoculated portion as well as provides a fungal bed cultivation method of a hon-shimeji mushroom which generates a fruit body from the fungal bed culture. According to the present invention, the formation rate of budlet in the fungal bed cultivation of a hon-shimeji mushroom is improved, thereby enabling stable production of a hon-shimeji mushroom in large scale commercial cultivation.
