Protein
Pneumolysin
Gene
ply, SP_1923
Organism
Streptococcus pneumoniae serotype 4 (strain ATCC BAA-334 / TIGR4)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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 By similarity.
