Abstract
A β-glycosidase SS-BGL mutant for modifying ginsenoside and application thereof are provided, which relate to the field of genetic engineering technologies. The β-glycosidase SS-BGL mutant is β-glycosidase SS-BGL with the amino acid sequence as shown in SEQ ID NO: 1 having mutation at one or more sites. A single-site mutation includes: A1, making glutamine at 96position of SEQ ID NO: 1 to be mutated to glutamic acid; A2, making asparagine at 97position of SEQ ID NO: 1 to be mutated to aspartate; A3, making asparagine at 128position of SEQ ID NO: 1 to be mutated to aspartate; A4, making asparagine at 302position of SEQ ID NO: 1 to be mutated to aspartate. A double-site mutation is a combination of A3 and A4, a three-site mutation is a combination of A1, A2 and A4, and a four-site mutation is a combination of A1, A2, A3 and A4.
