Description générale

Sphingomyelinase from Bacillus cereus (Bc-Smase) is a Mg2+-containing metalloenzyme. Bacillus cereus sphingomyelinase induces hemolysis of sheep erythrocytes.
Sphingomyelinase modulates adenosine triphosphate (ATP)-independent endocytosis of fibroblast and large vesicles of macrophages. Sphingomyelinase causes hemolysis of human erythrocytes. It is also a potent virulence factor leading to invasive diseases.

Application

Sphingomyelinase from Bacillus cereus has been used:
  • in the measurement of membrane capacitance in brain slices
  • for testing and confirming its silkworm-killing activity
  • in enzyme activity assay and for elucidating its effect on hydrolysis of sphingomyelin in complex lipid mixtures

Sphingomyelinase has been used in a study to investigate skeletal manifestations in pediatric and adult patients with Niemann Pick disease.

Actions biochimiques/physiologiques

Initiates the formation of sphingomyelin-based second messengers. Activates MAPK (mitogen-activated protein kinase) and SAPKs (stress-activated protein kinases); generates ceramide from sphingomyelin.

Définition de l'unité

One unit will hydrolyze 1.0 μmole of TNPAL-sphingomyelin per min at pH 7.4 at 37 °C.

Forme physique

Lyophilized powder containing potassium phosphate buffer salts and stabilizer.

Bacillus cereus sphingomyelinase (Bc-SMase) induces hemolysis of sheep erythrocytes which contain large amounts of sphingomyelin. We investigated the mechanism of this hemolysis in comparison to that induced by Clostridium perfringens alpha-toxin.
