Title:
1,3/1,4-XYLANASE MLX1034, GENE ENCODING SAME, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/156402
Kind Code:
A1
Abstract:
Provided are a 1,3/1,4-xylanase MLX1034, a gene encoding same, and an application thereof. The xylanase MLX1034 is isolated from Polaribacter sp. Q13, and has the amino acid sequence as shown in SEQ ID NO. 1, and the nucleotide sequence of the gene encoding the xylanase MLX1034 is as shown in SEQ ID NO. 2. The xylanase MLX1034 can specifically degrade 1,3/1,4-xylan to produce a xylo-oligosaccharide having a degree of polymerization greater than 1, has stable physical and chemical properties, can be reacted at room temperature, and is suitable for being widely applied in industrial production of red algae xylo-oligosaccharides, and energy cost in the production process can be effectively reduced.
