Metabolite Identification

Common Name

(N-acetylneuraminosyl(a2-6)lactosamine)

Description

(N-acetylneuraminosyl(alpha2-6)lactosamine) is widely distributed among tissues and is involved in biological processes such as the regulation of the immune response and the progression of colon cancer. Sialylation represents one of the most frequently occurring terminations of the oligosaccharide chains of glycoproteins and glycolipids. Sialic acid is commonly found alpha,6-linked to N-acetylgalactosamine (GalNAc). The biosynthesis of the linkage is mediated by a member of the sialyltransferase family, the beta-galactoside alpha,6-sialyltransferase (EC 2.4.99.1, ST6Gal.I). Although expressed by a single gene, this enzyme shows a complex pattern of regulation which allows its tissue- and stage-specific modulation. (PMID 11425186 )

6'-Sialyllactosamine is an oligosaccharide found in human milk. Oligosaccharides in human milk inhibit enteric pathogens in vitro and in vivo. (PMID:10683228 )

Enzymes

Enzyme Details

1. Beta-galactoside alpha-2,6-sialyltransferase 1

General function:: Not Available
Specific function:: Transfers sialic acid from the donor of substrate CMP-sialic acid to galactose containing acceptor substrates.
Gene Name:: ST6GAL1
Uniprot ID:: P15907
Molecular weight:: 46604.235

Reactions

Cytidine 5'-monophosphate-N-acetylneuraminic acid + beta-D-galactosyl-1,4-N-acetyl-beta-D-glucosamine → Cytidine monophosphate + (N-acetylneuraminosyl(a2-6)lactosamine)	details

Enzyme Details

2. Beta-galactoside alpha-2,6-sialyltransferase 2

General function:: Not Available
Specific function:: Transfers sialic acid from the donor of substrate CMP-sialic acid to galactose containing acceptor substrates. Has alpha-2,6-sialyltransferase activity toward oligosaccharides that have the Gal-beta-1,4-GlcNAc sequence at the non-reducing end of their carbohydrate groups, but it has weak or no activities toward glycoproteins and glycolipids.
Gene Name:: ST6GAL2
Uniprot ID:: Q96JF0
Molecular weight:: 60157.39

Reactions

Cytidine 5'-monophosphate-N-acetylneuraminic acid + beta-D-galactosyl-1,4-N-acetyl-beta-D-glucosamine → Cytidine monophosphate + (N-acetylneuraminosyl(a2-6)lactosamine)	details
