Abstract:
PURPOSE: An esterase KTL7 which is separated from the bottom of the sea is provided to enhance activities and to have stability in wide range of temperature. CONSTITUTION: An esterase KTL7 which is separated from the bottom of the sea has amino acid sequence of the sequence number 32(SEQ ID NO:32). A gene ciphering the esterase has the base sequence described in the sequence number 31. A manufacturing method of the esterase gene comprises the following steps: transforming the cells into recombinant vector which includes the esterase of the sequence number 31; culturing the transformed cells; and separating the esterase from the cultured cell. The novel esterase gene is obtained by the following steps: extracting environmental DNA from the deposit of the depth of 1,400 M; building a library by using fosmid vector; and separating the gene from a clone which is active in the tricaprulin flat medium.
