摘要:
The use is provided of a composition as a feed additive which comprises one or more endoglucanases, and 0-20% by weight, based upon the content of cellulase proteins in the composition, of a cellobiohydrolase. The endoglycanases may be one or more of EGI, EGII EGIII and any functionally active derivative of any thereof. Such endoglucanases may be obtained from a genetically modified strain of the fungus Trichoderma. Also provided is an enzyme-based feed additive which comprises EGI and/or EGII which lack the cellulose binding domain, and 0-20% by weight, based upon the content of cellulase proteins in the additive, of a cellobiohydrolase. A further enzyme-based feed additive is provided which comprises a cereal-based carrier, one or more endoglucanases, and 0-20% by weight, based upon the content of cellulase proteins in the additive, of a cellobiohydrolase. Such enzyme-based feed additives can be incorporated into a cereal-based feed which includes one or more of barley, wheat, tricale, rye and maize. The feed additive has the advantage of improving the feed conversion ratio and/or increasing the digestibility of a cereal-based feed in which it is included.
摘要:
The invention provides polynucleotides isolated from cDNA libraries of human fetal liver-spleen and macrophage as well as polypeptides encoded by these polynucleotides and mutants or variants thereof. The polypeptides correspond to a human CD39-like protein. Other aspects of the invention include vectors containing polynucleotides of the invention and related host cells as well a processes for producing CD39-like polypeptides, and antibodies specific for such polypeptides.

Two chitinases from Trichoderma harzianum P1 (ATCC 74058) show chitin-containing-fungus-inhibiting activity. One is an endochitinase and the other is a chitobiase. Both have molecular weights of 40 kDa and isoelectric points of 3.9. A &lgr;gtll recombinant encoding for the endochitinase has been prepared (ATCC 55338) and the gene encoding for the endochitinase has been removed from the DNA of the recombinant by the restriction enzyme, Not I. Endochitinases and chitobiases including the two purified from Trichoderma harzianum strain P1 demonstrate synergy with each other in anti-fungal effect.
摘要:
A composition is provided for ingestion by mammals for in vivo conversion of alpha-D-galactoside comprising an amount of alpha-galactosidase effective to hydrolyze alpha-D-galactoside to D-galactose, and non-toxic, ingestible excipient(s) for said alpha-galactosidase. Gastric distress in mammals due to ingestion of foods containing alpha-D-galactoside may be reduced by ingesting the foregoing composition of alpha-galactosidase and non-toxic, ingestible excipient contemporaneously with the ingestion of said food in an amount effective to hydrolyze the alpha-D-galactoside to D-galactose.
摘要:
The invention provides novel polynucleotides isolated from cDNA libraries of human fetal liver-spleen and macrophage as well as polypeptides encoded by these polynucleotides and mutants or variants thereof. The polypeptides correspond to a novel human CD39-like protein. Other aspects of the invention include vectors containing polynucleotides of the invention and related host cells as well a processes for producing novel CD39-like polypeptides, and antibodies specific for such polypeptides.
摘要:
Fabry disease results from an X-linked deficiency in the enzyme &agr;-galactosidase A. The present invention is directed to recombinant truncated forms of &agr;-galactosidase A, as well as therapeutic compositions comprising said truncated &agr;-galactosidase A which are useful, for example, to treat Fabry disease patients.
摘要:
Fabry disease results from an X-linked deficiency in the enzyme &agr;-galactosidase A. The present invention is directed to recombinant human &agr;-galactosidase A and provides baculovirus expression vectors and recombinant virus that provide stable expression of extracellular and intracellular levels of this enzyme in an insect cell culture. The recombinant-derived enzyme can be used in enzyme replacement therapy to treat Fabry patients. Composition useful in therapeutic administration of &agr;-galactosidase A are also provided.
摘要:
A method for inactivating a virion of an enveloped RNA virus comprising contacting the virion with an eosinophil-derived ribonuclease, such as eosinophil-derived neurotoxin (EDN) or eosinophil cationic protein (ECP). The invention also provides methods for treating a subject infected by an enveloped RNA virus and for preventing infection by an enveloped RNA virus comprising administering an effective amount of an eosinophil-derived ribonuclease, such as EDN or ECP. The invention also provides a composition comprising an effective amount of an eosinophil-derived ribonuclease and an acceptable carrier.
摘要:
The present invention is a process for reducing gelatin insolubles which includes providing a gelatin solution and adding to the gelatin solution amylase in an amount to provide a concentration of amylase of at least 0.1 ppm for a time sufficient to reduce gelatin insolubles. The present invention also provides a gelatin having a Bloom strength of from 60 to 400 and a concentration of amylase of greater than 0.1 ppm.
摘要:
The present invention aims to provide novel therapeutic agents for achondroplasia caused by mutations in FGFR3. Therapeutic agents for achondroplasia caused by the cartilage growth inhibition resulting from mutations in the gene for fibroblast growth factor receptor 3 (FGFR3), comprising a substance activating guanylyl cyclase B (GC-B) as an active ingredient are disclosed.
