Uniprot ID: P0C2J9

Gene Names: ply

Organism: Streptococcus pneumoniae serotype 4 (strain ATCC BAA-334 / TIGR4)


Expression Region: 2-471aa

Sequence Info: Full Length of Mature Protein

Source: Baculovirus

Tag Info: N-terminal 10xHis-tagged and C-terminal Myc-tagged

MW: 56.8 kDa

Alternative Name(s): Thiol-activated cytolysin

Relevance: Sulfhydryl-activated toxin that causes cytolysis by forming pores in cholesterol containing host membranes. After binding to target membranes, the protein undergoes a major conformation change, leading to its insertion in the host membrane and formation of an oligomeric pore complex. Cholesterol may be required for binding to host membranes, membrane insertion and pore formation. Can be reversibly inactivated by oxidation

Science 293:498-506(2001)

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.
