Enzyme Information

2.4.1.37

Fucosylgalactoside 3-alpha-galactosyltransferase.

based on mapping to UniProt P16442

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.

2.4.1.40

Glycoprotein-fucosylgalactoside alpha-N-acetylgalactosaminyltransferase.

based on mapping to UniProt P16442

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.
