FunFam 22: Histo-blood group ABO system transferase

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-acetyllactosaminide 3-alpha-galactosyltransferase. [EC: 2.4.1.87]
UDP-alpha-D-galactose + beta-D-galactosyl-(1->4)-beta-N-acetyl-D- glucosaminyl-R = UDP + alpha-D-galactosyl-(1->3)-beta-D-galactosyl- (1->4)-beta-N-acetylglucosaminyl-R.
  • Acts on beta-galactosyl-1,4-N-acetylglucosaminyl termini on asialo- alpha(1)-acid glycoprotein and N-acetyllactosamine (beta-D- galactosyl-1,4-N-acetyl-beta-D-glucosamine), but not on 2'-fucosylated-N-acetyllactosamine.
  • The non-reducing terminal N-acetyllactosamine residues of glycoproteins can also act as acceptor.
  • Formerly EC 2.4.1.124 and EC 2.4.1.151.

Glycoprotein-fucosylgalactoside alpha-N-acetylgalactosaminyltransferase. [EC: 2.4.1.40]
UDP-N-acetyl-alpha-beta-D-galactosamine + glycoprotein-alpha-L-fucosyl- (1->2)-D-galactose = UDP + glycoprotein-N-acetyl-alpha-D-galactosaminyl- (1->3)-(alpha-L-fucosyl-(1->2))-beta-D-galactose.
  • Acts on blood group substance H.
  • Can use a number of 2-fucosyl-galactosides as acceptors.

Fucosylgalactoside 3-alpha-galactosyltransferase. [EC: 2.4.1.37]
UDP-alpha-D-galactose + alpha-L-fucosyl-(1->2)-D-galactosyl-R = UDP + alpha-D-galactosyl-(1->3)-(alpha-L-fucosyl-(1->2))-D-galactosyl-R.
  • Acts on blood group substance, and can use a number of 2-fucosyl- galactosides as acceptors.

Globoside alpha-N-acetylgalactosaminyltransferase. [EC: 2.4.1.88]
UDP-N-acetyl-alpha-D-galactosamine + N-acetyl-D-galactosaminyl-(1->3)-D- galactosyl-(1->4)-D-galactosyl-(1->4)-D-glucosyl-(1<->1)-ceramide = UDP + N-acetyl-D-galactosaminyl-(1->3)-N-acetyl-D-galactosaminyl-(1->3)-D- galactosyl-(1->4)-D-galactosyl-(1->4)-D-glucosyl-(1<->1)-ceramide.
