IdeS Protein, Streptococcus pyogenes, Recombinant (His)

IdeS (IgG-degrading enzyme of Streptococcus pyogenes) is a secreted cysteine endopeptidase from the human pathogen S. pyogenes with an extraordinarily high degree of substrate specificity, catalyzing a single proteolytic cleavage at the lower hinge of human IgG. This proteolytic degradation promotes inhibition of opsonophagocytosis and interferes with the killing of group A Streptococcus. IdeS Protein, Streptococcus pyogenes, Recombinant (His) is expressed in E. coli expression system with His tag. The predicted molecular weight is 36.2 kDa and the accession number is F8V4V0-1.
