PROBLEM TO BE SOLVED: To provide a gene of α-L-fucosidase possessed by bifidobacteria, and to provide a microorganism group advantageous for colonization in the intestine and a novel containing α-L-fucose which is a factor that works advantageously against bifidobacteria Contribute to the provision of new oligosaccharides. An isolated gene encoding 1,2-α-L-fucosidase derived from Bifidobacterium, the nucleotide sequence shown in SEQ ID NO: 1 in the sequence listing or a part thereof, and 1,2 -an isolated gene encoding a portion having α-L-fucosidase enzyme activity, a recombinant vector containing an isolated gene encoding 1,2-α-L-fucosidase from Bifidobacterium, the set Provided are recombinants into which a replacement vector has been introduced, enzyme proteins produced using these recombinant vectors, and the like.
