s. pneumoniae

A cholesterol-dependent 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 is required for binding to host membranes, membrane insertion and pore formation; cholesterol binding is mediated by a Thr-Leu pair in the C-terminus. Can be reversibly inactivated by oxidation. Pneumolysin Protein, S. pneumoniae serotype 4, Recombinant (His) is expressed in yeast with N-6xHis tag. The predicted molecular weight is 54.8 kDa and the accession number is P0C2J9.

Part of an ATP-driven transport system. PsaA Protein, S. pneumoniae (strain ATCC BAA-255 R6), Recombinant (His & Myc) is expressed in E. coli expression system with N-10xHis and C-Myc tag. The predicted molecular weight is 40.0 kDa and the accession number is P0A4G3.

Part of an ABC transporter complex involved in manganese import. PsaA Protein, S. pneumoniae, Recombinant (His & Myc) is expressed in E. coli expression system with N-10xHis and C-Myc tag. The predicted molecular weight is 39.9 kDa and the accession number is P42363.
