일반 설명
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.
애플리케이션
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.
생화학적/생리학적 작용
Initiates the formation of sphingomyelin-based second messengers. Activates MAPK (mitogen-activated protein kinase) and SAPKs (stress-activated protein kinases); generates ceramide from sphingomyelin.
단위 정의
One unit will hydrolyze 1.0 μmole of TNPAL-sphingomyelin per min at pH 7.4 at 37 °C.
물리적 형태
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.

Niemann-Pick disease (NPD) due to acid sphingomyelinase deficiency is a lipid storage disease resulting from the accumulation of sphingomyelin, predominantly within cells of the monocyte-macrophage system. In contrast to other lysosomal storage disorders, skeletal involvement in NPD has not been

Bacillus cereus is one that causes of opportunistic human infections. Sphingomyelinase produced by B. cereus is assumed a virulence factor for the infection. Sphingomyelinase from Bacillus cereus (Bc-SMase) is Mg(2+)-containing metalloenzyme. Bc-SMase is a family of neutral SMase (nSMase) and
