  • Publication number: 20040072318
    Abstract: A novel enzyme which has an activity to release side chain carboxyl groups and ammonia from a protein by acting upon side chain amido groups in the protein. This invention relates to a method for the production of an enzyme, which comprises culturing in a medium a strain that belongs to a bacterium classified into Cytophagales or Actinomiycetes and has the ability to produce an enzyme having a property to deamidate amido groups in protein, thereby effecting production of said enzyme, and subsequently collecting said enzyme from the culture mixture. It also relates to a method for the modification of protein making use of a novel enzyme which directly acts upon amido groups in protein as well as to an enzyme which has a property to deamidate amido groups in protein and a gene which encodes said enzyme.

  • Publication number: 20020160500
    Abstract: The invention provides a glutaryl 7-ACA amidase from Pseudomonas diminuta strain BS-203, which catalyzes the hydrolysis of 7-&bgr;-(4-carboxybutanamido)-cephalosporanic acid to 7-aminocephalosporanic acid and glutaric acid. The invention also provides nucleic acid sequences, vectors, and host cells useful in the production of this amidase. The glutaryl 7-ACA amidase can be used for the preparation of 7-aminocephalosporanic acid.

  • Patent number: 6465204
    Abstract: A purified thermostable enzyme is derived from the archael bacterium Thermococcus GU5L5. The enzyme has a molecular weight of about 68.5 kilodaltons and has cellulase activity. The enzyme can be produced from native or recombinant host cells and can be used for the removal of arginine, phenylalanine, or methionine amino acids from the N-terminal end of peptides in peptide or peptidomimetic synthesis. The enzyme is selective for the L, or ‘natural’ enantiomer of the amino acid derivatives and is therefore useful for the production of optically active compounds. These reactions can be performed in the presence of the chemically more reactive ester functionally, a step which is very difficult to achieve with nonenzymatic methods.

  • Patent number: 6436396
    Abstract: Disclosed are polypeptides which originate from mammal, having L-asparaginase activity. The polypeptides are easily prepared by applying recombinant DNA techniques to DNAs encoding the polypeptides and they exert satisfactory effects in the treatment and/or the prevention for diseases caused by tumor cells dependent on L-asparagine, and cause no substantial serious side effects even when administered to humans in relatively-high dose.

  • Publication number: 20020090713
    Abstract: The present invention provides a novel D-aminoacylase, as well as method for producing a D-amino acid using the same. In order to achieve the above objective, the present inventors have succeeded in purifying heat-stable D-aminoacylase from microorganisms belonging to the genus Streptomyces by combining various purification methods. Furthermore, the present inventors found that the purified heat-stable D-aminoacylase is useful in industrial production of D-amino acids. By utilizing the heat-stable D-aminoacylase, it is possible to readily and efficiently produce the corresponding D-amino acids from N-acetyl-DL-amino acids (for example, N-acetyl-DL-methionine, N-acetyl-DL-valine, N-acetyl-DL-tryptophan, N-acetyl-DL-phenylalanine, N-acetyl-DL-alanine, N-acetyl-DL-leucine, and so on).

  • Patent number: 6395507
    Abstract: A process is provided for delaying the deactivation of glutaryl amidase during catalysis. The amidase is, after maximum conversion of a substrate, separated off by filtration and can be reused in a subsequent reaction batch. In each reaction cycle, the amidase loses activity. The inactivation of the amidase can be delayed by bringing it into contact with a thiol during the reaction. The thiol is preferably 2-mercaptoethanol or cysteine.
