PROBLEM TO BE SOLVED: To obtain a novel catalase gene which comprises the catalase gene that is a gene of Vibrio rumoiensis S-1 strain and contains a specific base sequence and is used for the production or the like of an enzyme useful in the antioxidation of foods or the like or the purification of contaminated water and/or soil. SOLUTION: This novel catalase gene is a gene of Vibrio rumoiensis S-1 strain, contains the base sequence represented by the formula and is used in the genetic engineering production or the like of catalase useful in the antioxidation of foods or the like or the purification of contaminated water and/or soil. This catalase gene is obtained by screening out a genomic library, assembled by treating a chromosomal DNA of Vibrio rumoiensis S-1 strain with a restriction enzyme and ligating the resultant DNA fragment to a plasmid, by means of using a partial DNA encoding the catalase of the above S-1 strain as a probe. |
