摘要:
The present invention is related to a polypeptide comprising an amino acid sequence, whereby the amino acid sequence of the polypeptide is at least 80% identical to a stretch of consecutive amino acids of the region of HPGGT comprising an amino acid sequence corresponding to SEQ.ID.No. 1, whereby such region is defined by (a) amino acid positions 150 to 200 of the amino acid sequence according to SEQ.ID.No. 1, or (b) amino acid positions 410 to 480 of the amino acid sequence according to SEQ.ID.No. 1, and whereby the polypeptide is suitable to elicit an immune response which is capable of inhibiting the catalytic activity of HPGGT.
摘要:
A method for inactivating enzymes, particularly enzymes found in human serum. The method comprises reacting the enzyme in a suitable medium, e.g. human serum, with an inactivating amount of peracetic acid. In the preferred embodiment the treated serum is subsequently neutralized and dialyzed. Preferably, the serums are used as standards for calibration or as a control in assay kits, e.g. RIA, and EIA or enzyme kits, for the determination of specific ligands and enzymes.

摘要:
A yeast extract containing 0.2% or more of γ-Glu-Abu based on dry weight of the yeast extract is produced by culturing a yeast, such as Saccharomyces cervisiae or Candida utilis, in a medium containing a compound selected from Abu (L-2-aminobutyric acid) and γ-Glu-Abu (L-γ-glutamyl-L-2-aminobutyric acid), and preparing a yeast extract from the obtained cells.

摘要:
Disclosed is a process for the enzymatic preparation of a gamma-glutamyl compound. The process comprises a step of contacting a gamma-glutamyl donor and a gamma-glutamyl acceptor with an aqueous medium comprising a gamma glutamyl transpeptidase enzyme. The enzyme is derived from a plant belonging to the Graminaceae or Leguminaceae family, or from Camellia sinensis.
摘要:
The present invention identifies the apoptosis-inducing protein of Helicobacter pylori, analyzes the structure and provides the amino acid sequence of the protein and the nucleotide sequence encoding the amino acid sequence. Furthermore, the present invention provides inhibiting agents of an apoptosis-inducing activity of the bacterium for the treatment of disease ascribed to the bacterium and a vaccine to prevent the infection of the bacterium. The present invention revealed that the apoptosis-inducing protein of Helicobacter pylon is a protein complex composed by association of two kinds of proteins, which comprise a part of the amino acid sequence encoded by γ-glutamyl transferase gene (HP1118). The present invention is said protein and a vaccine comprising said protein.
