Reaction: sphingosine 1-phosphate + H2O => sphingosine + orthophosphate [extracellular]

- in pathway: Sphingolipid metabolism
PPAP2A (phosphatidate phosphohydrolase type 2A) enzyme associated with the plasma membrane catalyzes the hydrolysis of extracellular sphingosine 1-phosphate to form sphingosine and orthophosphate (Roberts et al 1998).
