Sphinganine C4-monooxygenase

Sphinganine C4-monooxygenase (, sphingolipid C4-hydroxylase, SUR2 (gene), SBH1 (gene), SBH2 (gene)) is an enzyme with systematic name sphinganine,NADPH:oxygen oxidoreductase (C4-hydroxylating). This enzyme catalyses the following chemical reaction


 * sphinganine + NADPH + H+ + O2 $$\rightleftharpoons$$ phytosphingosine + NADP+ + H2O

Sphinganine C4-monooxygenase is involved in the biosynthesis of sphingolipids in yeast and plants.
