The enzyme sphinganine-1-phosphate aldolase () catalyzes the chemical reaction
This enzyme belongs to the family of lyases, specifically the aldehyde-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is sphinganine-1-phosphate palmitaldehyde-lyase (phosphoethanolamine-forming). Other names in common use include dihydrosphingosine 1-phosphate aldolase, sphinganine-1-phosphate alkanal-lyase, sphinganine-1-phosphate lyase, and sphinganine-1-phosphate palmitaldehyde-lyase. This enzyme participates in sphingolipid metabolism. It employs one cofactor, pyridoxal phosphate.
