  • Truncated and modified serratiopeptidase and polynucleotides encoding the same
    Patent number: 11499145
    Abstract: A truncated and modified Serratiopeptidase or a variant thereof, and polynucleotides encoding the same. The truncated and modified Serratiopeptidase may have an amino acid sequence including amino acids 1 to 344, and amino acids 1 to 380 of SEQ ID NO: 1. The truncated and modified Serratiopeptidase may further include a first Cysteine (C) residue at a N-terminus of the truncated and modified Serratiopeptidase, substituted for at least one of Alanine 8 and Leucine 12 of SEQ ID NO: 1; and a second Cysteine residue at a C-terminus of the truncated and modified Serratiopeptidase, substituted for at least one of Valine 339 and Arginine 302 of SEQ ID NO: 1. The first and the second Cysteine residues may be adapted to form at least one disulfide bond including at least one of C8-C339, and C12-C302 disulfide bonds between the N-terminus and the C-terminus of the truncated and modified Serratiopeptidase.
