EC 2.7.1.91

Names

Accepted name:
sphingosine kinase
Other names:
dihydrosphingosine kinase
dihydrosphingosine kinase (phosphorylating)
sphingosine kinase (phosphorylating)
SPHK1 (gene name)
SPHK2 (gene name)
sphingoid base kinase
sphinganine kinase
ATP:sphinganine 1-phosphotransferase
Systematic name:
ATP:sphingoid base 1-phosphotransferase

Reactions

Comments:

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.
