| 摘要 |
The present invention relates to a polypeptide which has ²-glucosidase activity, and which includes an amino acid sequence represented by SEQ ID NO: 1, a polypeptide including an amino acid sequence in which one or several amino acids are deleted, substituted, or added in the amino acid sequence represented by SEQ ID NO: 1, or a polypeptide including an amino acid sequence having 90% or greater sequence identity with the amino acid sequence represented by SEQ ID NO: 1. According to the present invention, a novel ²-glucosidase enzyme derived from Acremonium cellulolyticus, a polynucleotide encoding the ²-glucosidase, an expression vector for expressing the ²-glucosidase, a transformant incorporated with that expression vector, and a method for producing a cellulose degradation product using the ²-glucosidase can be provided. |
