Enzyme Information
| 2.7.1.91 |
Sphingosine kinase.
based on mapping to UniProt Q9NYA1
ATP + a sphingoid base = ADP + a sphingoid base 1-phosphate.
-!- The enzyme is involved in the production of sphingolipid metabolites. -!- It phosphorylates various sphingoid long-chain bases, such as sphingosine, D-erythro-dihydrosphingosine (sphinganine), phytosphingosine (4-hydroxysphinganine), 4-hydroxy-8-sphingenine, 4,8-sphingadienine and D-threo-dihydrosphingosine and L-threo- dihydrosphingosine. -!- The exact substrate range depends on the species.
