Enzymes

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
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
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
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

P17405
Molecular weight:
69935.53
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".
