Abstract

A xylosidase having improved enzymatic activity is disclosed. The amino acid sequence of the xylosidase is a modified amino acid sequence of SEQ ID NO: 2, wherein the modification is a substitution of phenylalanine at position 35 with glutamate, and/or a substitution of glutamine at position 41 with histidine.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A xylosidase consisting of a modified amino acid sequence of SEQ ID NO: 2, wherein the modification is a substitution of phenylalanine at position 35 with glutamate, and a substitution of glutamine at position 41 with histidine. 
     
     
       2. A xylosidase consisting of a modified amino acid sequence of SEQ ID NO: 2, wherein the modification is a substitution of phenylalanine at position 35 with glutamate. 
     
     
       3. A xylosidase consisting of a modified amino acid sequence of SEQ ID NO: 2, wherein the modification is a substitution of glutamine at position 41 with histidine.
