摘要： A property of a protein is modified by the following steps: (a) selecting 1000 or more genes from the genome of a first microorganism, and selecting 1000 or more genes from the genome of a second microorganism, wherein the genes from the first microorganism are orthologs to the genes from the second microorganism, and wherein the second microorganism is closely related to the first microorganism, but grows differently under at least one optimum growth condition when compared with the first microorganism, (b) comparing an amino acid sequence encoded by a gene from the first microorganism to an amino acid sequence encoded by the orthologous gene from the second microorganism, (c) detecting substitutions between the amino acid sequence encoded by a gene from the first microorganism and the amino acid sequence encoded by a gene from the second microorganism for each pair of orthologous genes, (d) compiling the detected amino acid substitutions for each amino acid substitution type, (e) calculating the frequency of each amino acid substitution type, wherein for each detected amino acid substitution type, a correction is made by subtracting the total number of substitution types which occur from the first microorganism to the second microorganism from the total number of the same substitution type which occurs in the reverse direction, or from the second microorganism to the first microorganism, (f) identifying and labelling the amino acid substitutions which occur at a high frequency as amino acid substitutions which are involved in said optimum growth condition, and (g) introducing one or more of the amino acid substitutions identified in (f) into the gene encoding the protein to modify a property of the protein.

摘要： The present invention provides a heat-stable enzyme having a DNA helicase activity, and preferably a structure-specific endonuclease activity. This enzyme can be obtained by cloning a gene encoding the enzyme from chromosomal DNA of a hyperthermophile, preferably a sulfur-metabolizing thermophilic archaebacteria, incorporating the gene into an expression vector, introducing the vector into a host such as Escherichia coli in the usual manner to create a transformant, and culturing the transformant.
