ENZYME entry: EC 2.7.1.91

Accepted Name
Sphingosine kinase.
Alternative Name(s)
Dihydrosphingosine kinase.
Sphinganine kinase.
Sphingoid base kinase.
Reaction catalysed
ATP + a sphingoid base <=> ADP + a sphingoid base 1-phosphate
Comment(s)
  • 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.
