Abstract: The present invention relates to novel aminoglycoside antibiotics, a process for producing the same, and pharmaceutical use thereof. More specifically, the present invention relates to compounds represented by formula (I), a process for producing the same, and use of the same as antimicrobial agents. wherein R represents amino or hydroxyl.

Abstract: An object is to efficiently produce thermostable catalase at low cost by expressing it as a recombinant protein in large quantity. A recombinant microorganism capable of efficiently expressing thermostable catalase can be provided by obtaining a DNA necessary for efficiently producing it as a recombinant protein, and the thermostable catalase can be efficiently produced at low cost by cultivating the obtained recombinant microorganism. Hydrogen peroxide can be efficiently decomposed at low cost, even at high temperature, by treating a solution containing hydrogen peroxide with the thermostable catalase of the present invention.

Abstract: Disclosed are a ketoreductase mutant which can be used for an efficient production of daunorubicin derivatives, a DNA encoding the mutant, a transformant prepared by introducing the DNA thereinto to produce a daunorubicin derivative, and a process of producing a daunorubicin derivative using the transformant. The ketoreductase mutant has an amino acid sequence in which one amino acid residue or two or more amino acid residues selected from the group consisting of amino acids located at positions corresponding to the 42nd, 149th, 153rd, 270th, and 306th amino acids in the amino acid sequence of a ketoreductase (EvaE) from a chlororemomycin-producing bacterium (Amycolatopsis orientalis) are substituted with another amino acid residues.

Abstract: A novel endoglucanase PPCE derived from Penicillium pinophilum, a cellulase preparation containing the endoglucanase PPCE, and a method of treating a cellulose-containing fabric utilizing the endoglucanase PPCE or the cellulase preparation, are disclosed. The endoglucanase PPCE is highly active to a fabric, and has a low optimum temperature and a strongly acidic optimum pH.

Abstract: A fusion collagenase in which an affinity tag is added to the carboxyl terminal of a collagenase was expressed as a recombinant protein. It was found that a collagenase having a collagen-binding domain can be selectively collected by purifying the obtained fusion collagenase by affinity chromatography.
