摘要:
A polynucleotide encoding a polypeptide which lowers the glucose side chain amount in a serotype-specific polysaccharide antigen of Streptococcus mutans ; novel Streptococcus mutans strain having the above polynucleotide; an antibody specific to this Streptococcus mutans strain; and a method of detecting the above-described Streptococcus mutans strain occurring in a subject sample. According to this method, it is possible to examine the presence or absence of Streptococcus mutans of an untypable serotype in a subject sample to thereby specify a subject having a high risk of the onset of infective endocarditis.
摘要:
The present invention relates to genes for enzymes having the activity of transferring a methyl group to lignans, plants with an altered lignan composition using these methyltransferases, and so on. More particularly, the present invention relates to enzyme genes having the activity of synthesizing methylated lignans, preferably enzyme genes having the activity of synthesizing sesame-derived methylated lignans, and use thereof.
摘要:
The present invention relates to ammonia transporter genes and use thereof. The invention relates in particular to a brewer's yeast which shows enhanced ammonia assimilation, alcoholic beverages produced using such yeast, and a method of producing such alcoholic beverages. More specifically, the invention relates to the MEP1 gene which codes for the ammonia transporter Mep1 in brewer's yeast, particularly to a yeast which can control the ammonia assimilation ability by controlling the level of expression of the nonScMEP1 gene or ScMEP1 gene characteristic to beer yeast and to a method of producing alcoholic beverages using such yeast.
摘要:
The present invention relates to a gene encoding a protein having a trehalose synthesis-promoting activity and use thereof, in particular, a yeast for practical use with superior resistance property to dryness and/or low-temperature storage, alcoholic beverages produced with said yeast, and a method for producing said beverages. More particularly, the present invention relates to a yeast, whose resistance property to dryness and/or resistance property to low-temperature storage is enhanced by amplifying expression level of TSL1 gene encoding a protein Tsl1p having a trehalose synthesis-promoting activity in brewer's yeast, especially non-ScTSL1 gene specific to a lager brewing yeast and to a method for producing alcoholic beverages with said yeast, etc.
摘要:
A method for processing a sprouted cereal in which an enzymatic activity in the sprouted cereal is reduced by bringing the sprouted cereal into contact with water vapor.
摘要:
The present invention provides methods for producing human ceramide in a yeast cell. The methods of the present invention comprise: 1) introducing the sphingoid Δ4-desaturase gene (DES1) by transformation of the yeast cell; and 2) abolishing the expression of the yeast sphinganine C4-hydroxylase gene (SUR2) by transformation of the yeast cell.
摘要:
It is intended to provide ACE inhibitory tripeptides which are not easily digested by digestive enzymes after being orally taken and thus have fewer tendencies to lose their ACE inhibitory activity in vivo . More specifically, 3 tripeptides having an ACE inhibitory activity and showing a hypotensive effect in an animal experiment are discovered from a thermolysin digestion product of sesame. These tripeptides respectively have amino acid sequences Leu-Ser-Ala, Val-Ile-Tyr and Leu-Val-Tyr and show an angiotensin converting enzyme inhibitory activity.
摘要:
It is intended to provide a novel flavone C-glycoside derivative or its salt showing, in particular, an antiallergic effect and a composition containing the same. Allergic diseases have been increasing in the recent years. Among all, pollenosis and atopic dermatitis are remarkably increasing to thereby result in social problems. Flavones and glycosides thereof, which are reported as having an effect of inhibiting the release of histamine from adipocytes and an immunosuppressive effect, are expected as being applicable as remedies for allergy. However, most of flavones should be taken in a large dose to exert the effects and, therefore, it has been urgently required to find out a compound exhibiting the effects at a smaller dose. Under these circumstances, it is intended to provide a novel component whereby allergic diseases can be treated in a small dose and a composition containing the same.
摘要:
The present invention relates to a composition for controlling scab disease in agricultural products, which comprises a compound of Formula I or a salt thereof. The present invention further relates to a method for controlling scab disease in agricultural products by using a composition for controlling scab disease, which comprises a compound of Formula I or a salt thereof.
摘要:
The present invention relates to an instrument, a method and a kit for detecting a microorganism contaminating a subject test sample, which enables one to quickly and accurately identify the microorganism with an easy operation. The instrument for detecting a microorganism according to the present invention relates to a microarray type instrument in which oligonucleotides prepared based on nucleotide sequences specific to the species and genus to which the subject microorganism belongs have been immobilized onto a surface of a substrate. Based on the presence or absence of hybridization of the probes prepared from the test sample with the oligonucleotides immobilized onto the surface of the substrate, the present invention makes it possible to detect and/or identify the microorganism in the test sample easily, quickly and accurately.
