Description

Cer(d18:1/14:0), also known as N-tetradecanoyl-sphing-4-enine, is a ceramide (Cer). Ceramides are members of the class of compounds known as sphingolipids (SPs), or glycosylceramides. SPs are lipids containing a backbone of sphingoid bases (e.g. sphingosine or sphinganine) that are often covalently bound to a fatty acid derivative through N-acylation. SPs are found in cell membranes, particularly in peripheral nerve cells and the cells found in the central nervous system (including the brain and spinal cord). Sphingolipids are extremely versatile molecules that have functions controlling fundamental cellular processes such as cell division, differentiation, and cell death. Impairments associated with sphingolipid metabolism are associated with many common human diseases such as diabetes, various cancers, microbial infections, diseases of the cardiovascular and respiratory systems, Alzheimer’s disease and other neurological syndromes. The biosynthesis and catabolism of sphingolipids involves a large number of intermediate metabolites where many different enzymes are involved. Simple sphingolipids, which include the sphingoid bases and ceramides, make up the early products of the sphingolipid synthetic pathways, while complex sphingolipids may be formed by the addition of head groups to the ceramide template (Wikipedia). In humans, ceramides are phosphorylated to ceramide phosphates (CerPs) through the action of a specific ceramide kinase (CerK). Ceramide phosphates are important metabolites of ceramides as they act as a mediators of the inflammatory response. Ceramides are also one of the hydrolysis byproducts of sphingomyelins (SMs) through the action of the enzyme sphingomyelin phosphodiesterase, which has been identified in the subcellular fractions of human epidermis (PMID: 25935 ) and many other tissues. Ceramides can also be synthesized from serine and palmitate in a de novo pathway and are regarded as important cellular signals for inducing apoptosis (PMID: 14998372 ). Ceramides are key in the biosynthesis of glycosphingolipids and gangliosides. In terms of its appearance and structure, Cer(d18:1/14:0) is a colorless solid that consists of an unsaturated 18-carbon sphingoid base with an attached saturated tetradecanoyl fatty acid side chain. In most mammalian SPs, the 18-carbon sphingoid bases are predominant (PMID: 9759481 ).

Enzymes

Enzyme Details

1. Galactocerebrosidase

General function:: Involved in galactosylceramidase activity
Specific function:: Hydrolyzes the galactose ester bonds of galactosylceramide, galactosylsphingosine, lactosylceramide, and monogalactosyldiglyceride. Enzyme with very low activity responsible for the lysosomal catabolism of galactosylceramide, a major lipid in myelin, kidney and epithelial cells of small intestine and colon.
Gene Name:: GALC
Uniprot ID:: P54803
Molecular weight:: 77062.86

Enzyme Details

2. Globoside alpha-1,3-N-acetylgalactosaminyltransferase 1

General function:: Involved in transferase activity, transferring hexosyl groups
Specific function:: Catalyzes the formation of some glycolipid via the addition of N-acetylgalactosamine (GalNAc) in alpha-1,3-linkage to some substrate. Glycolipids probably serve for adherence of some pathogens
Gene Name:: GBGT1
Uniprot ID:: Q8N5D6
Molecular weight:: 40126.9

Enzyme Details

3. N-acetylglucosaminyl-phosphatidylinositol de-N-acetylase

General function:: Involved in N-acetylglucosaminylphosphatidylinositol de
Specific function:: Involved in the second step of GPI biosynthesis. De-N-acetylation of N-acetylglucosaminyl-phosphatidylinositol.
Gene Name:: PIGL
Uniprot ID:: Q9Y2B2
Molecular weight:: 28530.965

Enzyme Details

4. Phosphatidylcholine:ceramide cholinephosphotransferase 2

General function:: Involved in catalytic activity
Specific function:: Bidirectional lipid cholinephosphotransferase capable of converting phosphatidylcholine (PC) and ceramide to sphingomyelin (SM) and diacylglycerol (DAG) and vice versa. Direction is dependent on the relative concentrations of DAG and ceramide as phosphocholine acceptors. Directly and specifically recognizes the choline head group on the substrate. Also requires two fatty chains on the choline-P donor molecule in order to be recognized efficiently as a substrate. Does not function strictly as a SM synthase. Required for cell growth
Gene Name:: SGMS2
Uniprot ID:: Q8NHU3
Molecular weight:: 42279.8

Enzyme Details

5. Phosphatidylcholine:ceramide cholinephosphotransferase 1

General function:: Involved in catalytic activity
Specific function:: Bidirectional lipid cholinephosphotransferase capable of converting phosphatidylcholine (PC) and ceramide to sphingomyelin (SM) and diacylglycerol (DAG) and vice versa. Direction is dependent on the relative concentrations of DAG and ceramide as phosphocholine acceptors. Directly and specifically recognizes the choline head group on the substrate. Also requires two fatty chains on the choline-P donor molecule in order to be recognized efficiently as a substrate. Does not function strictly as a SM synthase. Suppresses BAX-mediated apoptosis and also prevents cell death in response to stimuli such as hydrogen peroxide, osmotic stress, elevated temperature and exogenously supplied sphingolipids. May protect against cell death by reversing the stress-inducible increase in levels of proapoptotic ceramide. Required for cell growth
Gene Name:: SGMS1
Uniprot ID:: Q86VZ5
Molecular weight:: 49207.3

Enzyme Details

6. 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

7. Ceramide glucosyltransferase

General function:: Cell wall/membrane/envelope biogenesis
Specific function:: Catalyzes the first glycosylation step in glycosphingolipid biosynthesis, the transfer of glucose to ceramide. May also serve as a "flippase".
Gene Name:: UGCG
Uniprot ID:: Q16739
Molecular weight:: 44853.255

Enzyme Details

8. Phosphatidylinositol N-acetylglucosaminyltransferase subunit Q

General function:: Involved in phosphatidylinositol N-acetylglucosaminyltransferase activity
Specific function:: Part of the complex catalyzing the transfer of N-acetylglucosamine from UDP-N-acetylglucosamine to phosphatidylinositol, the first step of GPI biosynthesis.
Gene Name:: PIGQ
Uniprot ID:: Q9BRB3
Molecular weight:: 65343.25

Enzyme Details

9. Phosphatidylinositol N-acetylglucosaminyltransferase subunit A

General function:: Involved in biosynthetic process
Specific function:: Necessary for the synthesis of N-acetylglucosaminyl-phosphatidylinositol, the very early intermediate in GPI-anchor biosynthesis.
Gene Name:: PIGA
Uniprot ID:: P37287
Molecular weight:: 54126.065

Enzyme Details

10. Phosphatidylinositol N-acetylglucosaminyltransferase subunit H

General function:: Involved in phosphatidylinositol N-acetylglucosaminyltr
Specific function:: Part of the complex catalyzing the transfer of N-acetylglucosamine from UDP-N-acetylglucosamine to phosphatidylinositol, the first step of GPI biosynthesis.
Gene Name:: PIGH
Uniprot ID:: Q14442
Molecular weight:: 21080.415
