Comments
Comment typeDescription
Biophysicochemical PropertiespH dependence: Optimum pH is 6.5-7.5.;
Catalytic ActivitySphingomyelin + H(2)O = N-acylsphingosine + phosphocholine.
CofactorName=Mg(2+); Xref=ChEBI
FunctionConverts sphingomyelin to ceramide. Hydrolyze 1-acyl-2- lyso-sn-glycero-3-phosphocholine (lyso-PC) and 1-O-alkyl-2-lyso- sn-glycero-3-phosphocholine (lyso-platelet-activating factor). The physiological substrate seems to be Lyso-PAF.
PathwayLipid metabolism; sphingolipid metabolism.
SimilarityBelongs to the neutral sphingomyelinase family.
Subcellular LocationMembrane; Multi-pass membrane protein.
