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.

This proteolytic degradation promotes inhibition of opsonophagocytosis and interferes with the killing of group A Streptococcus. IdeS Protein, Streptococcus pyogenes, Recombinant (His & GST) is expressed in E. coli expression system with His and GST tag. The predicted molecular weight is 63.1 kDa and the accession number is F8V4V0-1.

CRISPR-Cas9 Protein, Streptococcus pyogenes, Recombinant (His) is expressed in Baculovirus insect cells with His tag. The predicted molecular weight is 163 kDa and the accession number is Q99ZW2.

Important streptococcal virulence factor which cleaves human fibronectin and degrades vitronectin. Also cleaves human IL1B precursor to form biologically active IL1B. Can induce apoptosis in human monocytes and epithelial cells in vitro, and reduces phagocytic activity in monocytic cells. Thus, may play a role in bacterial colonization, invasion, and inhibition of wound healing. Streptopain Protein, S. pyogenes serotype M28, Recombinant (His & SUMO) is expressed in E. coli expression system with N-6xHis-SUMO tag. The predicted molecular weight is 43.6 kDa and the accession number is Q48R29.

Group B Streptococcus (GBS) causes invasive infections in human newborns. the GBS β-protein attenuates innate immune responses by binding to sialic acid-binding immunoglobulin-like lectin 5 (Siglec-5), an inhibitory receptor on phagocytes.the polymorphism could influence the risk of prematurity among human fetuses of mothers colonized with GBS. This first functionally proven example of a paired receptor system in the Siglec family has multiple implications for regulation of host immunity.

CAMP factor is an extracellular cytolytic protein produced by Streptococcus agalactiae. CAMP factor binds the Fc fragments of IgG and is also known as protein B, in analogy to protein A of Staphylococcus aureus.
