摘要:
Described herein are novel gene sequences isolated from Trichoderma reesei. Two genes encoding proteins comprising a cellulose binding domain, one encoding an arabinofuranosidase and one encoding an acetylxylanesterase are described. The sequences CIP1 and CIP2 contain a cellulose binding domain. These proteins are especially useful in the textile and detergent industry and in pulp and paper industry.

摘要:
Compositions and methods for protecting a plant from a pathogen, particularly a fungal pathogen, are provided. Compositions include novel amino acid sequences, and variants and fragments thereof, for antipathogenic polypeptides that were isolated from microbial fermentation broths. Nucleic acid molecules comprising nucleotide sequences that encode the antipathogenic polypeptides of the invention are also provided. A method for inducing pathogen resistance in a plant using the nucleotide sequences disclosed herein is further provided. The method comprises introducing into a plant an expression cassette comprising a promoter operably linked to a nucleotide sequence that encodes an antipathogenic polypeptide of the invention. Compositions comprising an antipathogenic polypeptide or a transformed microorganism comprising a nucleic acid of the invention in combination with a carrier and methods of using these compositions to protect a plant from a pathogen are further provided. Transformed plants, plant cells, seeds, and microorganisms comprising a nucleotide sequence that encodes an antipathogenic polypeptide of the invention, or variant or fragment thereof, are also disclosed.
摘要:
The invention relates to an antibiotic substance of microbial origin, arbitrarily denominated antibiotic 107891 which is produced by fermentation of Microbispora sp. ATCC PTA-5024, the pharmaceutically acceptable salts and compositions thereof, and their use as an antibacterial agent having inhibitory activity versus susceptible microbes. Antibiotic 107891, which is a complex comprising two Factors, denominated Factors Al and A2, has a peptide structure containing lanthionine and methyllanthionine as constituents which are typical characteristics of the antibiotics of the lantibiotics group. Antibiotic 107891 and its Factors Al and A2 show a good antibacterial activity against Gram-positive bacteria including methicillin resistant and van comycin resistant strains, and is active also against some Gram-negative bacteria such as M. catharralis, Neisseria species and H. influenzae and Mycobacteria.
摘要:
The present invention relates to a method for increasing the efficiency of targeted integration of a polynucleotide to a pre-determined site into the genome of a filamentous fungal cell with a preference for NHR, wherein said polynucleotide has a region of homology with said pre-determined site, comprising steering an integration pathway towards HR. The present invention also relates to a mutant filamentous fungus originating from a parent cell, said mutant having an HR pathway with elevated efficiency and/or an NHR pathway with a lowered efficiency and/or a NHR/HR ratio with decreased efficiency as compared to said HR and/or NHR efficiency and/or NHR/HR ratio of said parent cell under the same conditions.
摘要:
A substantially pure, isolated antigenic protein originating in fungi of the genus Malassezia, characterized by having an avidity with IgE antibodies originating in allergic patients; antigenic fragments originating in said protein; a specific antibody against said antigenic protein or fragments; a diagnostic, therapeutic or prophylactic agent for malassezian allergic diseases containing the antigenic protein or fragments as the active ingredient; a novel recombinant malassezian antigenic protein; a gene coding for the protein; and epitopes of the protein.
摘要:
This invention relates to Glycine-rich protein (Glyrichin), as well as its coding gene and application, especially relates to the application for antibacterial purpose. The Glyrichin of the present invention are at least one selected from the following protein families: proteins having amino acid residues in Sequence 1, 3-14 in the Sequence List or protein with antibacterial activities having 1 to 20 amino acid residues of sequence 1, 3-14 being deleted, inserted and/or substituted and with 1 to 20 amino acid residue sequences being added to the carboxyl terminal or amino terminal of Sequence 1 and 3-14 of the Sequence List correspondingly. The Glyrichin of the present invention and the coding gene can be applied to antibacterial purpose, such as the preparation of drugs for prevention and/or treatment of human or livestock infectious bacterial diseases; for the preparation of products for prevention and/or treatment of potentially infectious bacterial diseases of different kinds of creatures; for the production of transgenic creatures which can defend against diseases and pests; for the preparation of the derivatives, antagonists as well as its ligands and antibodies of Glyrichin.
