Abstract
A method for selectively obtaining a natural variant of an enzyme having activity includes (1) a step of detecting an ORF sequence of a protein having enzyme activity from a genome database including base sequences of metagenomic DNA of environmental microbiota; (2) a step of obtaining at least one PCR clone including the ORF sequence having a full length, a partial sequence of the ORF sequence, or a base sequence encoding an amino acid sequence which is formed by deletion, substitution, or addition of at least one amino acid residue in an amino acid sequence encoded by the ORF sequence, by performing PCR cloning on at least one metagenomic DNA of the environmental microbiota by using a primer designed based on the ORF sequence; (3) a step of determining a base sequence and an amino acid sequence which is encoded by the base sequence for each PCR clone obtained in the step (2); and (4) a step of selecting a natural variant of an enzyme having activity by measuring enzyme activity of proteins encoded by each PCR clone obtained in the step (2).
