RC STRAIN=4947 {ECO:0000313|EMBL:BAV54145.1}; RX PubMed=27825483; DOI=10.1016/j.micres.2016.08.011; RA Suzuki T., Nagano T., Niwa K., Mutoh S., Uchino M., Tomizawa M., Sagane Y., RA Watanabe T.; RT "Isolation of botulinolysin, a thiol-activated hemolysin, from serotype D RT Clostridium botulinum: A species-specific gene duplication in Clostridia."; RL Microbiol. Res. 193:20-29(2016). CC -!- FUNCTION: A cholesterol-dependent toxin that causes cytolysis by CC forming pores in cholesterol containing host membranes. After binding CC to target membranes, the protein undergoes a major conformation change, CC leading to its insertion in the host membrane and formation of an CC oligomeric pore complex. Cholesterol is required for binding to host CC membranes, membrane insertion and pore formation; cholesterol binding CC is mediated by a Thr-Leu pair in the C-terminus. Can be reversibly CC inactivated by oxidation. {ECO:0000256|RuleBase:RU364025}. CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi- CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}. Secreted CC {ECO:0000256|RuleBase:RU364025}. Host cell membrane CC {ECO:0000256|RuleBase:RU364025}; Multi-pass membrane protein CC {ECO:0000256|RuleBase:RU364025}. CC -!- SIMILARITY: Belongs to the cholesterol-dependent cytolysin family.
