abstract：:Human legumain was characterized following overexpression in a murine cell line as the C-terminal Ig-fusion protein. Upon acid treatment, the prolegumain autoproteolyzed distal to two aspartic acid residues to yield a highly active form. The ability of mature legumain to cleave after aspartic acid residues was confirm...
