  • Patent number: 8877915
    Abstract: Disclosed are: transcription regulatory factors capable of regulating the transcription or expression of genes for mannanases or cellulases, as mentioned below; and others. Specifically disclosed is a protein selected from the following proteins (a), (b) and (c): (a) a protein comprising the amino acid sequence depicted in SEQ ID NO:2; (b) a protein which comprises an amino acid sequence produced by deleting, substituting or adding one or several amino acid residues (e.g., 1 to 5 amino acid residues) in the amino acid sequence depicted in SEQ ID NO:2 and which is capable of regulating the transcription of genes for mannanases or cellulases; and (c) a protein which comprises an amino acid sequence having a 70% or higher sequence identity to the amino acid sequence depicted in SEQ ID NO:2 and which is capable of regulating the transcription of genes for mannanases or cellulases, or a partial fragment of the protein. Also specifically disclosed are a gene encoding the protein, and others.

  • Patent number: 8877463
    Abstract: The present invention relates to Rhodanobacter ginsenosidimutans KCTC22231T-derived ginsenoside glycosidase and use thereof. The polypeptide has an activity of converting PPD (protopanaxadiol)-type saponins into in vivo absorbable and highly active deglycosylated saponins, by selective hydrolysis of a bond at a particular position of ginsenoside. The present invention also relates an amino acid sequence constituting the polypeptide, a nucleic acid sequence encoding the protein, a recombinant vector comprising the nucleic acid sequence, and a transformant transformed with the vector. The invention further provides a method for preparing Rhodanobacter ginsenosidimutans KCTC22231T-derived ginsenoside glycosidase by culturing the transformant, a method for converting PPD (protopanaxadiol)-type major ginsenoside into a rare ginsenoside that is absorbable in vivo using the protein, and a composition for converting PPD-type saponins into in vivo absorbable saponins, having the protein as an active ingredient.

  • Patent number: 8871491
    Abstract: The present invention encompasses a novel S. aureus bioconjugate vaccine. More generally, the invention is directed to Gram-positive and other bioconjugate vaccines containing a protein carrier, at least one polysaccharide such as a capsular Gram-positive polysaccharide, and, optionally, an adjuvant or pharmaceutically acceptable carrier. The instant invention also includes methods of producing Gram-positive and other bioconjugate vaccines. An N-glycosylated protein is also provided that contains one or more polysaccharides such as Gram-positive polysaccharides. The invention is additionally directed to engineered prokaryotic organisms comprising nucleotide sequences encoding a glycosyltransferase of a first prokaryotic organism and a glycosyltransferase of a second prokaryotic organism. The invention further includes plasmids and prokaryotic cells transformed with plasmids encoding polysaccharides and enzymes which produce an N-glycosylated protein and/or bioconjugate vaccine.
