	4.1.2.27
Description	Sphinganine-1-phosphate aldolase.
Alternative names	Sphingosine-1-phosphate lyase; Sphingosine phosphate lyase
Catalyzed reaction	Sphinganine 1-phosphate = phosphoethanolamine + palmitaldehyde.
Cofactor	Pyridoxal-phosphate.
	The enzyme controls the concentration of sphingosine 1-phosphate, a key sphingolipid second messenger involved in the regulation of cell proliferation, motility, invasiveness, and apoptosis.
