The invention relates to a marine-derived collagen expansion protease VP9 and its encoding gene and application. A marine Vibrio strain, Vibrio pomeroyi strain 12613, was deposited in the China Center for Type Culture Collection on March 6, 2020, address: Wuhan University, Wuhan, China, and its strain collection number is CCTCC NO: 2020050. A gene encoding collagen expansion protease VP9, the nucleotide sequence is shown in SEQ ID No. 1; the collagen expansion protease VP9 expressed by the encoding gene, the amino acid sequence is shown in SEQ ID No. 2. The collagen swelling protease VP9 in the present invention has a significant swelling function on collagen, but has no degrading activity on collagen, and has great application potential in the swelling treatment of collagen in leather processing industry and other fields. |
