摘要:
This invention relates to an isolated nucleic acid fragment encoding a metalloprotease, more specifically peptide deformylase. The invention also relates to the construction of a recombinant DNA construct encoding all or a portion of peptide deformylase, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of peptide deformylase in a transformed host cell.
摘要:
Genes and proteins involved in the biosynthesis of lipopeptides by microorganisms, in particular the nucleic acids forming the biosynthetic locus for the A54145 lipopeptide from Streptomyces fradiae and the A54145-like lipopeptide from Streptomyces refuineus. These nucleic acids can be used to make expression constructs and transformed host cells for the production of lipopeptides. The genes and proteins allow direct manipulation of lipopeptides and related chemical structures via chemical engineering of the proteins involved in the biosynthesis of A54145.
摘要:
A single polypeptide is provided which comprises first and second domains. The first domain enables the polypeptide to cleave one or more vesicle or plasma-membrane associated proteins essential to exocytosis, and the second domain enables the polypeptide to be translocated into a target cell or increases the solubility of the polypeptide, or both. The polypeptide thus combines useful properties of a clostridial toxin, such as a botulinum or tetanus toxin, without the toxicity associated with the natural molecule. The polypeptide can also contain a third domain that targets it to a specific cell, rendering the polypeptide useful in inhibition of exocytosis in target cells. Fusion proteins comprising the polypeptide, nucleic acids encoding the polypeptide and methods of making the polypeptide are also provided. Controlled activation of the polypeptide is possible and the polypeptide can be incorporated into vaccines and toxin assays.
摘要:
The invention relates to recombinant plasmid pSP1 harboring the gene vapk, which encodes alkalic protease VapK, and par gene, which is associated with the stability of plasmid, a microorganism Vibrio metschnikovii transformed therewith, and method for producing an alkaline protease VapK using the same microorganism.
摘要:
This invention relates to an isolated nucleic acid fragment encoding an SSE1 protein. The invention also relates to the construction of a chimeric gene encoding all or a portion of the SSE1 protein, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the SSE1 protein in a transformed host cell. The present invention also relates to methods using the SSE1 protein in modulating formation of storage organelles and storage compounds in seeds, and in discovering compounds with potential herbicidal activity.
摘要:
The GapC plasmin binding protein genes of Streptococcus dysgalactiae (S. dysgalactiae), Streptococcus agalactiae (S. agalactiae), Streptococcus uberis (S. uberis), Streptococcus parauberis (S. parauberis), and Streptococcus iniae (S. iniae) are described, as well as the recombinant production of the GapC proteins therefrom. Also described is the use of the GapC proteins from those species in vaccine compositions to prevent or treat bacterial infections in general, and mastitis in particular.
