Function and Biology Details

Reactions catalysed:
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
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
