Hemolysin

Function

Hemolysin (HL) is exotoxin from bacteria which causes lysis of red blood cells^[1].

alpha-hemolysin is a transmembrane pore-forming heptameric molecule^[2]. See details for in Pore forming toxin, α-hemolysin.
delta-hemolysin is a 26 amino acid peptide from the bacterium Staphylococcus exhibiting antimicrobial activity against Legionerlla ^[3].

See details of hemolysin E in Molecular Playground/ClyA.

For toxins in Proteopdia see Toxins.

Relevance

HL acts as a virulence factor in the pathogenesis of invasive infections^[4].
