Compound as reactive (1)
sphingosine + ATP → sphingosine 1-phosphate + H+ + ADP
Compound as product (1)
H2O + sphingosine 1-phosphate → phosphate + sphingosine
Reversible reaction (2)
sphingosine + UDP-α-D-galactose ↔ H+ + O-galactosylsphingosine + UDP
CDP-choline + sphingosine ↔ CMP + H+ + sphingosylphosphorylcholine
