摘要:
The invention provides a method for the quantification of a biomolecule in a complex mixture of biomolecules which comprises a fractionation of the mixture of biomolecules providing at least two fractions with at least one distinct component each. These fractions are then subjected to serial combinatorial dilution. Subsequently, the biomolecule is detected and identified in the fractions by a method providing a sensitivity threshold and identify information. The quantity of the biomolecule is determined by summarizing the number of identifications of the biomolecule in each fraction on each dilution level in consideration of the respective dilution factor. For purpose of normalization this sum may be divided by the total number of identifications of all biomolecules in all fractions on all dilution levels.
摘要:
The present invention relates to 25 hitherto undescribed genes of B. licheniformis and gene products derived therefrom and all sufficiently homologous nucleic acids and proteins thereof. They occur in five different metabolic pathways for the formation of odorous substances. The metabolic pathways in question are for the synthesis of: 1) isovalerian acid (as part of the catabolism of leucine), 2) 2-methylbutyric acid and/or isobutyric acid (as part of the catabolism of valine and/or isoleucine), 3) butanol and/or butyric acid (as part of the metabolism of butyric acid), 4) propyl acid (as part of the metabolism of propionate) and/or 5) cadaverine and/or putrescine (as parts of the catabolism of lysine and/or arginine). The identification of these genes allows biotechnological production methods to be developed that are improved to the extent that, to assist these nucleic acids, the formation of the odorous substances synthesized via these metabolic pathways can be reduced by deactivating the corresponding genes in the micro-organism used for the biotechnological production. In addition, these gene products are thus available for preparing reactions or for methods according to their respective biochemical properties.
摘要:
The invention relates to five or four novel genes and the gene products thereof from Bacillus licheniformis and sufficiently similar genes and proteins which are involved in vivo in the formation of polyamino acids. The gene in question is ywsC, ywsC′, ywtA, ywtB and ywtD or proteins coded thereby. The gene ywsC, ywsC′, ywtA and ywtB can be used to improve biotechnological production methods by microorganisms, wherein they are functionally inactivated; the gene ywtD which codes for a peptide decomposing poly-gamma glutamate can, inversely, contribute to the improvement of biotechnological production methods by increased expression. Said genes can be used positively, preferably to result in a modification or decomposition of poly-gamma glutamate.

The aim of the invention is to improve the secretion of a protein from a host cell in order to increase the product yield of protein in a fermentation process. This is achieved by an expression vector comprising a promoter sequence and a nucleic acid sequence that codes for a protein. The protein comprises a signal peptide and an additional amino acid sequence, and the signal peptide comprises an amino acid sequence that is at least 80% identical to the amino acid sequence specified SEQ ID NO: 2, at least 80% identical to the amino acid sequence specified in SEQ ID NO: 4, at least 80% identical to the amino acid sequence specified in SEQ ID NO: 6, or the signal peptide comprises an amino acid sequence that is structurally homologous to at least one of said sequences.

The aim is to increase the protein product yield in microbial fermentation. This is achieved by a method which introduces into a microorganism not only a first expression construct which encodes the protein, but also a second expression construct which encodes an auxiliary protease which differs from the protein, is proteolytically active and which comprises an amino acid sequence which is at least 50% identical to the amino acid sequence indicated in SEQ ID NO. 1.

The invention relates to a protein VanB involved, in Gram-positive bacteria, in resistance to glycopeptides, particularly to vancomycine, said resistance being of the type inducible by the vancomycine and non-inducible by teicoplanine. The invention also relates to the utilisation of fragments of nucleotides of the gene van B for the detection of resistances to glycopeptides.
