'''Hemolysin''' (HL) is exotoxin from bacteria which causes lysis of red blood cells<ref>PMID:20110774</ref>. Hemolysin from the bacterium ''Clostridium'' are called '''alpha-toxin''' (AT).  AT is a zinc metalloenzyme and binds to the membrane in the presence of calcium. It acts as a phospholipase C.

*'''alpha-hemolysin''' is a transmembrane pore-forming heptameric molecule<ref>PMID:8943190</ref>.  See details for in [[Pore forming toxin, α-hemolysin]].
