2.7.1.91

Accepted name:

sphingosine kinase

Reaction:

ATP + a sphingoid base = ADP + a sphingoid base 1-phosphate

Other name(s):

SPHK1 (gene name); SPHK2 (gene name); dihydrosphingosine kinase; dihydrosphingosine kinase (phosphorylating); sphingosine kinase (phosphorylating); sphingoid base kinase; sphinganine kinase; ATP:sphinganine 1-phosphotransferase

Systematic name:

ATP:sphingoid base 1-phosphotransferase

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.
