Description

D-erythro-sphingosylphosphorylcholine is an intermediate in Sphingolipid metabolism. D-erythro-sphingosylphosphorylcholine is the 5th to last step in the synthesis of Digalactosylceramidesulfate and is converted from Sphingosine via the enzyme sphingosine cholinephosphotransferase ( EC 2.7.8.10). It is then converted to Sphingomyelin via the enzyme sphingosine N-acyltransferase (EC 2.3.1.24).

Enzymes

Enzyme Details

1. Sphingomyelin phosphodiesterase

General function:: Involved in hydrolase activity
Specific function:: Converts sphingomyelin to ceramide. Also has phospholipase C activities toward 1,2-diacylglycerolphosphocholine and 1,2-diacylglycerolphosphoglycerol. Isoform 2 and isoform 3 have lost catalytic activity.
Gene Name:: SMPD1
Uniprot ID:: P17405
Molecular weight:: 69935.53

Enzyme Details

2. Galactosylgalactosylxylosylprotein 3-beta-glucuronosyltransferase 1

General function:: Involved in galactosylgalactosylxylosylprotein 3-beta-glucuronosyltransferase activity
Specific function:: Involved in the biosynthesis of L2/HNK-1 carbohydrate epitope on glycoproteins. Can also play a role in glycosaminoglycan biosynthesis. Substrates include asialo-orosomucoid (ASOR), asialo-fetuin, and asialo-neural cell adhesion molecule. Requires sphingomyelin for activity: stearoyl-sphingomyelin was the most effective, followed by palmitoyl-sphingomyelin and lignoceroyl-sphingomyelin. Activity was demonstrated only for sphingomyelin with a saturated fatty acid and not for that with an unsaturated fatty acid, regardless of the length of the acyl group (By similarity).
Gene Name:: B3GAT1
Uniprot ID:: Q9P2W7
Molecular weight:: 38255.675

Enzyme Details

3. Ectonucleotide pyrophosphatase/phosphodiesterase family member 7

General function:: Involved in catalytic activity
Specific function:: Converts sphingomyelin to ceramide. Also has phospholipase C activity toward palmitoyl lyso-phosphocholine. Does not appear to have nucleotide pyrophosphatase activity.
Gene Name:: ENPP7
Uniprot ID:: Q6UWV6
Molecular weight:: 51493.415

Enzyme Details

4. Sphingomyelin phosphodiesterase 2

General function:: Involved in metal ion binding
Specific function:: Converts sphingomyelin to ceramide. Hydrolyze 1-acyl-2-lyso-sn-glycero-3-phosphocholine (lyso-PC) and 1-O-alkyl-2-lyso-sn-glycero-3-phosphocholine (lyso-platelet-activating factor). The physiological substrate seems to be Lyso-PAF.
Gene Name:: SMPD2
Uniprot ID:: O60906
Molecular weight:: 47645.29

Enzyme Details

5. Proactivator polypeptide

General function:: Involved in lipid metabolic process
Specific function:: Saposin-D is a specific sphingomyelin phosphodiesterase activator (EC 3.1.4.12)
Gene Name:: PSAP
Uniprot ID:: P07602
Molecular weight:: 58112.1

Enzyme Details

6. 1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase delta-3

General function:: Involved in calcium ion binding
Specific function:: Hydrolyzes the phosphatidylinositol 4,5-bisphosphate (PIP2) to generate 2 second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3). DAG mediates the activation of protein kinase C (PKC), while IP3 releases Ca(2+) from intracellular stores. Essential for trophoblast and placental development. May participate in cytokinesis by hydrolyzing PIP2 at the cleavage furrow.
Gene Name:: PLCD3
Uniprot ID:: Q8N3E9
Molecular weight:: 89257.54

Enzyme Details

7. Sphingomyelin phosphodiesterase 3

General function:: Involved in metal ion binding
Specific function:: Catalyzes the hydrolysis of sphingomyelin to form ceramide and phosphocholine. Ceramide mediates numerous cellular functions, such as apoptosis and growth arrest, and is capable of regulating these 2 cellular events independently. Also hydrolyzes sphingosylphosphocholine. Regulates the cell cycle by acting as a growth suppressor in confluent cells. Probably acts as a regulator of postnatal development and participates in bone and dentin mineralization.
Gene Name:: SMPD3
Uniprot ID:: Q9NY59
Molecular weight:: 71080.1

Enzyme Details

8. Sphingomyelin phosphodiesterase 4

General function:: Involved in metal ion binding
Specific function:: Catalyzes the hydrolysis of membrane sphingomyelin to form phosphorylcholine and ceramide.
Gene Name:: SMPD4
Uniprot ID:: Q9NXE4
Molecular weight:: 86192.575

Enzyme Details

9. Non-lysosomal glucosylceramidase

General function:: Involved in catalytic activity
Specific function:: Non-lysosomal glucosylceramidase that catalyzes the conversion of glucosylceramide to free glucose and ceramide. Involved in sphingomyelin generation and prevention of glycolipid accumulation. May also catalyze the hydrolysis of bile acid 3-O-glucosides, however, the relevance of such activity is unclear in vivo.
Gene Name:: GBA2
Uniprot ID:: Q9HCG7
Molecular weight:: 104648.13

Enzyme Details

10. Sphingomyelin synthase-related protein 1

General function:: Involved in sphingomyelin biosynthetic process
Specific function:: Not Available
Gene Name:: SAMD8
Uniprot ID:: Q96LT4
Molecular weight:: 48320.2
