Zusammenfassung:PROBLEM TO BE SOLVED: To provide a new gluconic acid dehydratase having industrially practical heat stability and storage stability and capable of efficiently forming an aldonic acid into a corresponding 2-keto-3-deoxyaldonic acid, to provide a gene encoding the gluconic acid dehydratase, to provide the 2-keto-3-deoxyaldonic acid, by using a transformed cell containing the gluconic acid dehydratase or the gene, and to provide a method for producing a 2-deoxyaldonic acid or a 2-deoxyaldose of which the carbon number is decreased by one. SOLUTION: This new gluconic acid dehydratase derived from Achromobacter xylosoxidans and the gene encoding the same are provided, respectively. The transformed cell containing the gluconic acid dehydratase or the gene is used for producing the corresponding 2-keto-3-deoxyaldonic acid, by being made to act on the aldonic acid.
