ENSG00000174684	O43505	MAR00889: paragloboside + UDP-N-acetylglucosamine --> H+ + nLc5Cer + UDP	ENSG00000170340 or ENSG00000174684 or ENSG00000176383 or ENSG00000179913	Pending No, the gene is not relevant to the reaction provided. Analysis and explanation. The gene ENSG00000174684 encodes for a beta-1,4-glucuronyltransferase involved in the O-mannosylation of alpha-dystroglycan (DAG1), where it transfers a glucuronic acid residue onto a xylose acceptor to produce the glucuronyl-beta-1,4-xylose-beta disaccharide primer. This function is related to the synthesis of phosphorylated O-mannosyl glycan, necessary for binding extracellular proteins with high affinity. In contrast, the provided reaction involves the conversion of paragloboside to nLc5Cer, which is unrelated to the function of the gene, as it involves different substrates and products. The gene's activity is specific to the O-mannosylation process, not the synthesis pathway described in the provided reaction.	No

Analysis and explanation: The gene ENSG00000102595 encodes for a protein involved in the quality control of protein folding in the endoplasmic reticulum by reglucosylating misfolded glycoproteins. Its catalytic activity involves the reglucosylation of N-glycans on misfolded proteins. However, the provided reaction describes the conversion of D-galactosyl-N-acylsphingosine and UDP-galactose to digalactosylceramide, H+, and UDP, which does not involve N-glycan reglucosylation nor is it related to the protein folding quality control process. Therefore, the gene's function and catalytic activity do not relate to the provided reaction.	No

Analysis and explanation: The function and catalytic activity of the gene ENSG00000134910 are associated with the transfer of a glycan to an asparagine residue in nascent polypeptide chains during N-glycosylation. This process involves the oligosaccharyl transferase (OST) complex and does not relate to the reaction described, which involves the conversion of D-galactosyl-N-acylsphingosine and UDP-galactose to digalactosylceramide, H+, and UDP. The specific reaction described entails sphingolipid metabolism, not protein N-glycosylation.	No

Analysis and explanation: The gene ENSG00000163527 encodes the catalytic subunit of the oligosaccharyl transferase (OST) complex, which is involved in the process of N-glycosylation of nascent polypeptides in the endoplasmic reticulum. Its function is to transfer a glycan from dolichol-pyrophosphate to an asparagine residue within a specific consensus motif. In contrast, the provided reaction describes the transfer of a galactose from UDP-galactose to D-galactosyl-N-acylsphingosine to form digalactosylceramide. These reactions involve different substrates, products, enzymes, and biological processes, thus making the gene not relevant to the provided reaction.	No

Analysis and explanation: The gene ENSG00000119227 codes for a mannosyltransferase involved in glycosylphosphatidylinositol (GPI) anchor biosynthesis, specifically transferring a fourth mannose to trimannosyl-GPIs. The reaction provided involves the transformation of D-galactosyl-N-acylsphingosine and UDP-galactose into digalactosylceramide, H+, and UDP, which does not involve GPI anchor biosynthesis or mannosyltransferase activity. Thus, the gene and the reaction are not related.	No

The reaction described involves the synthesis of digalactosylceramide from D-galactosyl-N-acylsphingosine and UDP-galactose, which is not related to the function of the enzyme encoded by the gene.	No

Analysis and explanation. The gene ENSG00000175711 codes for a glycosyltransferase that galactosylates queuosine(34) in tRNA(Tyr), using UDP-alpha-D-galactose. The provided reaction involves the conversion of D-galactosyl-N-acylsphingosine and UDP-galactose into digalactosylceramide, H+, and UDP, which is unrelated to the specific tRNA modification described for the gene's product.

Analysis and explanation: The gene ENSG00000139044 encodes an enzyme that transfers N-acetylgalactosamine (GalNAc) from UDP-GalNAc to N-acetylglucosamine-beta-benzyl, forming N,N'-diacetyllactosediamine with a beta-1,4-linkage in N-linked and possibly O-linked glycans. However, the reaction provided involves D-galactosyl-N-acylsphingosine and UDP-galactose to form digalactosylceramide, which is not the same substrate or product involved in the gene's annotated catalytic activity.

Analysis and explanation: The gene ENSG00000060642 encodes an enzyme that functions as an alpha-1,6-mannosyltransferase involved in glycosylphosphatidylinositol-anchor biosynthesis. This means it transfers a mannose to the glycosylphosphatidylinositol (GPI) during GPI precursor assembly. However, the provided reaction involves the conversion of D-galactosyl-N-acylsphingosine and UDP-galactose to digalactosylceramide, H+, and UDP, which involves galactosyltransferase activity, not mannosyltransferase activity.

The gene ENSG00000162885 encodes a Beta-1,3-N-acetylgalactosaminyltransferase that participates in the synthesis of a specific carbohydrate structure on N- and O-glycans and is involved in alpha-dystroglycan glycosylation. Its catalytic activity involves the formation of a trisaccharide structure on protein O-mannose. On the other hand, the provided reaction describes the conversion of D-galactosyl-N-acylsphingosine and UDP-galactose to digalactosylceramide.

Analysis and explanation. The gene ENSG00000172461 encodes a protein that catalyzes the transfer of fucose from GDP-beta-L-fucose to N-acetyl glucosamine within glycan structures. In contrast, the reaction provided involves the transfer of galactose from UDP-galactose to D-galactosyl-N-acylsphingosine to form digalactosylceramide, which does not involve fucose or the specific substrates and products catalyzed by the gene's protein.

Analysis and explanation. The gene ENSG00000176383 codes for a Beta-1,3-N-acetylglucosaminyltransferase that specifically functions in synthesizing poly-N-acetyllactosamine through the addition of N-acetyl-beta-D-glucosaminyl residues to beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl derivatives. This is evidenced by its catalytic activity which involves the reaction between a beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl derivative and UDP-N-acetyl-alpha-D-glucosamine. However, the reaction provided¡ªD-galactosyl-N-acylsphingosine + UDP-galactose forming digalactosylceramide¡ªis entirely different in terms of substrates, products, and type of glycosylation, indicating no involvement of the Beta-1,3-N-acetylglucosaminyltransferase encoded by ENSG00000176383.

Analysis and explanation: The gene ENSG00000147162 encodes a protein that functions as an O-GlcNAc transferase, catalyzing the transfer of an N-acetylglucosamine from UDP-GlcNAc to serine or threonine residues of proteins, which is different from the reaction involving the transfer of galactose to ceramide to form digalactosylceramide.

The catalytic activity described for the gene's product involves the reglucosylation of specific N-glycans. In contrast, the reaction provided involves the conversion of D-galactosyl-N-acylsphingosine and UDP-galactose to digalactosylceramide, H+, and UDP, which is unrelated to the function and catalytic activity of the gene's product.

However, the provided reaction involves the transfer of D-galactose from UDP-galactose to D-galactosyl-N-acylsphingosine, producing digalactosylceramide.

My knowledge about glycosphingolipid metabolism is very limited, so I really hope that someone with relevant background can help review it. 👀🌹

[hhl-24]

ALL of these seem fine to me.

[JHL-452b]

Could you please help us to review this issue? @feiranl

[feiranl]

@edkerk Ed, Could you also help review this issue due to your expertise in lipid metabolism, Thanks!

[feiranl]

As far as I can see I would say the GPT review and manual check are correct.

[edkerk]

I'll have a final check as well, tbd next week
