Staphylococcus aureus beta toxin

Staphylococcus aureus beta toxin is a toxin produced by Staphylococcus aureus.[1] It is a form of sphingomyelinase[2] called sphingomyelinase C. This enzyme is toxic to a variety of cells, including erythrocytes, fibroblasts, leukocytes, and macrophages. Susceptible cells are subject to lysis of exposed sphingomyelin on their membrane surfaces.[3]

The beta toxin exhibits maximum activity at 10°C, at 37°C (normal body temperature) seems to be inactive.
