Uniprot ID: Q48R29

Gene Names: speB

Organism: Streptococcus pyogenes serotype M28 (strain MGAS6180)


Expression Region: 146-398aa

Sequence Info: Full Length

Source: E.coli

Tag Info: N-terminal 6xHis-SUMO-tagged

MW: 43.6 kDa

Alternative Name(s): Exotoxin type B SPE B Streptococcal cysteine proteinase Streptococcus peptidase A Short name: SPP

Relevance: 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

Purity: Greater than 90% as determined by SDS-PAGE.

Storage Buffer: Tris-based buffer,50% glycerol

Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
