摘要:
The present invention relates to the intersection of the fields of immunology and protein engineering, and particularly to antigens and vaccines useful in prevention of infection by human papilloma virus. Provided are recombinant protein antigens, compositions, and methods for the production and use of such antigens and vaccine compositions.
摘要:
The present invention relates to a cellulose-degrading enzyme composition comprising one or more cellobiohydrolase and/or endoglucanase enzyme, and an effective amount of an isolated GH16 polypeptide, where the presence of the isolated GH16 polypeptide in the enzyme composition increases the rate or extent of degradation of a cellulosic substrate compared to an equivalent dosage of a corresponding cellulose-degrading enzyme composition lacking the at least one isolated GH16 polypeptide. The present invention also relates to a method for producing fermentable sugars from a cellulosic substrate using the above cellulose- degrading enzyme composition and to genetically modified microbes for produced the above cellulose-degrading enzyme composition.
摘要:
Recombinant carrier molecules having amino acid sequences from thermostable enzymes and methods of use for expression, recovery and delivery of foreign sequences (peptides and polypeptides) produced in different systems (bacteria, yeast, DNA, cell cultures such as mammalian, plant, insect cell cultures, protoplast and whole plants in vitro or in vivo are provided. The recombinant carrier molecule using sequences from lichenase B (Lic B) were also made and used it as part of carrier protein to express, recover and deliver a variety of target polypeptides of interest.
摘要:
The aim of the invention is to extend the field of application of beta -glucanases, which are usually used in a slightly acidic to neutral environment, so that they are also stable enough in alkaline conditions to be used in technical processes which are carried out in such conditions. According to the invention, an enzyme obtained from Bacillus alkalophilus DSM 9956, which shows glucanolytic action can be used.
摘要:
The present invention relates to a method for solubilisation or hydrolysis of Municipal Solid Waste (MSW) with an enzyme blend and an enzyme composition for solubilization of Municipal Solid Waste (MSW), the enzyme composition comprising a cellulolytic background composition and a protease,lipase and/or beta-glucanase.
摘要:
The present invention provides isolated and purified genes which are differentially expressed during banana fruit development, and the protein products of these genes. The present invention further provides DNA regulatory elements which are differentially expressed during banana fruit development, chimeric genes comprising these DNA regulatory elements operably linked to heterologous DNA molecules, and plants transformed with said chimeric genes, providing for controlled expression of said heterologous DNA molecules during the development and ripening of the fruit of said plants, or in response to exogenous ethylene signals in said plants. The present invention also provides a method for expression of a heterologous protein in fruit comprising transforming fruiting plants with one or more chimeric genes according to the present invention, exposing said fruit to an endogenous or exogenous ethylene signal, and harvesting fruit containing said heterologous protein. The method of the present invention may further comprise isolating the proteins produced by said method from the harvested fruit. In a particularly preferred embodiment, the heterologous proteinis a therapeutic protein, which may be isolated from the harvested fruit, or consumed directly in the transformed fruit by a patient in need of said therapeutic protein.
摘要:
The invention relates to a process for the production of alcoholic beverages such as beer or whiskey with a mixture of enzymes comprising an endo- beta (1,4)-xylanase, an arabinofuranosidase, an alpha-amylase, an endo-protease and a beta -(1,3; 1,4)-glucanase, and optionally, a saccharifying amylase and/or an exopeptidase. Preferable are mixtures in which the enzymes which are necessary in the brewing process are provided by transgenic seeds. Only a minor amount of malt may be necessary for flavour and colour.
摘要:
The present invention provides recombinant or chimaeric DNA molecules comprising plant SAR genes, wherein the wild-type genes corresponding to said SAR genes can be chemically induced in a plant in a protein-synthesis independent or in a protein-synthesis dependent manner. Methods for obtaining these DNA molecules are also provided. Additionally, the present invention provides chemically inducible wheat genes, Arabidopsis chitinase IV, Maize PR-1mz, and Maize thaumatin PR-5mz. The anti-pathogenic sequences according to the invention can be genetically engineered and transformed into plants to obtain transgenic plants with enhanced resistance to disease. In one embodiment of the present invention, the chemically regulatable DNA promoter sequence of the Arabidopsis Pr-1 gene is provided. Another aspect of the present invention is a method of improving protection of a plant against a pest comprising transgenically expressing in said plant two or more DNA molecules encoding anti-pathogenic proteins, wherein the transgenically expressed proteins exert a synergistic effect.
