Abstract: The amino acid sequence of a mutant which is obtained by introducing a novel mutation into a Pseudonocardia thermophila JCM3095-derived nitrile hydratase consisting of two types of heterogeneous subunits, and the base sequence of the gene are provided. The nitrile hydratase is modified by specifying the region to be modified in the stereostructure/amino acid sequence of the nitrile hydratase, and applying alteration such as substitution, insertion, deletion or the like, to the amino acids in the amino acid sequence which are corresponding to the amino acid residues forming the region. Also provided is a method for modifying an enzyme having a nitrile hydratase activity.

Abstract: A novel gluconate dehydratase derived from Achromobacter xylosoxidans and a gene encoding the gluconate dehydratase are provided. By reacting the gluconate dehydratase or a transformed cell containing the gene with an aldonic acid, the corresponding 2-keto-3-deoxyaldonic acid can be efficiently produced.

Abstract: A method for producing a pyrimidine nucleoside compound includes reacting a sugar phosphate and pyrimidine base derivative using an enzyme having cytosine nucleoside phosphorylase activity, the pyrimidine base derivative being represented by general formula (I): (wherein R1 represents an amino group that may be replaced with an acyl group having an alkyl group of 1 to 3 carbon atoms or an alkyl group of 1 to 3 carbon atoms, an alkyl group of 1 to 3 carbon atoms, or a thiol group; R2 represents an amino group, a thiol group, a hydroxyl group, or a hydrogen atom; R3 represents an alkyl group of 1 to 3 carbon atoms that may be replaced with a hydroxyl group, an amino group, or a hydrogen atom; R4 represents a hydroxyl group or a hydrogen atom; when R1 is an amino group, when R2 is a hydroxyl group, and when R4 is a hydrogen atom; R3 is neither an alkyl group of 1 to 3 carbon atoms nor a hydrogen atom).

Abstract: Optically active chroman-3-acetic acids and optically active chroman-3-acetic acid esters can be obtained by treating a mixture of (3R)- and (3S)-chroman-3-acetic esters of formula (I) Äwherein R1 is a straight or branched alkyl group having 1-5 carbon atoms and R2 is a hydrogen atom or substituted or unsubstituted amino groupÜ is treated with an esterase which has an optically selective hydrolyzing activity or microorganisms which carry said hydrolase, or a preparation therefrom. A novel esterase derived from bacteria of genus Pseudonocardia can also be used as said esterase.

Abstract: The present invention is aimed at providing the amino acid sequence of a nitrile hydratase having a novel mutation point, and the base sequence of the gene. It is also aimed at providing a method for modifying an enzyme having a nitrile hydratase activity. As a means to achieve the above objects, the amino acid sequence of a mutant which is obtained by introducing a novel mutation into a Pseudonocardia thermophila JCM3095-derived nitrile hydratase consisting of two types of heterogeneous subunits, and the base sequence of the gene are provided. Further, the nitrile hydratase is modified by specifying the region to be modified in the stereostructure/amino acid sequence of the nitrile hydratase, and applying alteration such as substitution, insertion, deletion or the like, to the amino acids in the amino acid sequence which are corresponding to the amino acid residues forming the region. According to the invention, it is possible to convert a nitrile compound to a corresponding amide compound more efficiently compared with the prior art.

Abstract: The invention provides a method for producing a cytosine nucleoside compound from pentose-1-phosphate and cytosine or a derivative thereof using a nucleoside phosphorylase reactive to cytosine or a bacterium having the enzyme activity. The invention also provides a method for specifically reducing an activity to degrade the substrates or the product, resulting in efficient production of the cytosine nucleoside compound. According to the invention, little by-product is produced in producing cytonucleocide compounds.
