FunFam 28: beta-1,4-galactosyltransferase 1

There are 4 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
N-acetyllactosamine synthase. [EC: 2.4.1.90]
UDP-alpha-D-galactose + N-acetyl-D-glucosamine = UDP + N-acetyllactosamine.
  • The reaction is catalyzed by a component of EC 2.4.1.22, which is identical with EC 2.4.1.38, and by an enzyme from the Golgi apparatus of animal tissues.
  • Formerly EC 2.4.1.98.

Beta-N-acetylglucosaminylglycopeptide beta-1,4-galactosyltransferase. [EC: 2.4.1.38]
UDP-alpha-D-galactose + N-acetyl-beta-D-glucosaminylglycopeptide = UDP + beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminylglycopeptide.
  • Terminal N-acetyl-beta-D-glucosaminyl residues in polysaccharides, glycoproteins and glycopeptides can act as acceptor.
  • High activity is shown toward such residues in branched-chain polysaccharides when these are linked by beta-1,6 links to galactose residues; lower activity toward residues linked to galactose by beta- 1,3 links.
  • A component of EC 2.4.1.22.

Lactose synthase. [EC: 2.4.1.22]
UDP-alpha-D-galactose + D-glucose = UDP + lactose.
  • The enzyme is a complex of 2 proteins A and B.
  • In the absence of the B protein (alpha-lactalbumin) the enzyme catalyzes the transfer of galactose from UDP-galactose to N-acetylglucosamine (cf. EC 2.4.1.90).

Neolactotriaosylceramide beta-1,4-galactosyltransferase. [EC: 2.4.1.275]
UDP-alpha-D-galactose + N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D- galactosyl-(1->4)-beta-D-glucosyl-(1<->1)-ceramide = UDP + beta-D- galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl- (1->4)-beta-D-glucosyl-(1<->1)-ceramide.
