General annotation (Comments)

Function	Cleaves phosphorylated sphingoid bases (PSBs), such as sphingosine-1-phosphate, into fatty aldehydes and phosphoethanolamine. Elevates stress-induced ceramide production and apoptosis By similarity.
Catalytic activity	Sphinganine 1-phosphate = phosphoethanolamine + palmitaldehyde.
Cofactor	Pyridoxal phosphate By similarity.
Pathway	Lipid metabolism; sphingolipid metabolism.
Subcellular location	Endoplasmic reticulum membrane; Single-pass type III membrane protein By similarity.
Sequence similarities	Belongs to the group II decarboxylase family. Sphingosine-1-phosphate lyase subfamily.
