    摘要: A class of subtilisin analogs suitable for admixture to cleaning compositions and having improved stability over naturally occurring Bacillus subtilisins are prepared by expressing a modified gene encoding the subtilisin analog in Bacillus subtilis. The subtilisin analogs are characterized as having a modified calcium binding site to improve calcium binding and either an Asn or a Gly replaced in any Asn-Gly sequences present in the subtilisin.

    摘要: A novel alkaline protease having the same amino acid sequence as protease derived from Bacillus licheniformis excluding at lease one of 105th and 221st amino acids, i.e., aspartic acid and glutamic in place of the glycin and methioninc, respectively. The protease is useful as detergents.

    摘要: Zur Gewinnung von Subtilisin werden Bakterien des Genus Bacillus in einem Fermenter auf synthetischem Medium kultiviert, wobei in einer ersten Anwachsphase mit einer NH₄-Anfangskonzentration von 0,5 bis 150 mM, insbesondere 1 bis 50 mM und Nachdosierung der C-Quelle für die Aufrechterhaltung ihrer Konzentra­tion im Bereich von 100 mM bis 1 M bis zum Absinken der Ammoniumkonzentration unter einen N-limitierenden Wert in der Kultur zwischen 0,05 und 2 mM, insbeson­dere 0,1 und 0,3 mM gearbeitet wird, wonach der N-­limitierende Wert der Ammoniumkonzentration aufrecht­erhalten und der Gehalt der C-Quelle zwischen 10 mM und 2 M eingestellt wird bis zum Ende der Produk­tionsphase, wonach das gebildete Subtilisin abge­sondert wird. Als C-Quelle werden insbesondere Glycerin, Acetat oder Hexosen verwendet. Vorzugsweise wird die Biomassekonzentration im Medium durch Nach­füttern von C-Quelle erhöht. Ein Sauerstoffpartial­druck über der Kultur von > 11,5 Pa ist zweckmäßig. Als Proteaseproduzent dient insbesondere Bacillus licheniformis DSM 1969.

    摘要: Novel methods and novel industrial unicellular microorganism strains, particularly industrial Bacillus strains, are provided for enhanced production of endogenous and exogenous polypeptides. Cloning vehicles containing one or more copies of the gene expressing the polypeptide of interest are introduced into a compatible host, the transformed hosts treated to form protoplasts and then fused with protoplast acceptors prepared from industrial strains. Efficient transfer of the vehicle containing the genes of interest is achieved, with the resulting modified industrial strains being effective producers of the desired polypeptide product.

    摘要: The present invention relates to method for screening chemically modified mutant enzymes for amidase and/or esterase activity. This method includes providing a chemically modified mutant enzyme with one or more amino acid residues from an enzyme being replaced by cysteine residues, where at least some of the cysteine residues are modified by replacing thiol hydrogen in the cysteine residues with a thiol side chain, contacting the chemically modified mutant enzyme with a substrate for an amidase and/or a substrate for an esterase and determining whether the chemically modified mutant enzyme exhibits amidase and/or esterase activity. The presentinvention also relates to chemically modified mutant enzymes and a method for producing them where one or more amino acid residues from an enzyme are replaced by cysteine residues, and the cysteine residues are modified by replacing at least some of the thiol hydrogen in the cysteine residue with a thiol side chain to form the chemically modified mutant enzyme. The thiol side chain is selected from the group consisting of -SCH2(p-CH3-C6H4), -SCH2(p-OCH3-C6H4), -SCH2(p-CF3-C6H4), and -SCH2(2,4-diNO2-C6H3).
