DE   O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase.
AN   O-fucosylpeptide beta-1,3-N-acetylglucosaminyltransferase.
CA   (1) 3-O-(alpha-L-fucosyl)-L-seryl-[EGF-like domain protein] + UDP-N-
CA   acetyl-alpha-D-glucosamine = 3-O-(N-acetyl-beta-D-glucosaminyl-(1->3)-
CA   alpha-L-fucosyl)-L-seryl-[EGF-like domain protein] + H(+) + UDP.
CA   (2) 3-O-(alpha-L-fucosyl)-L-threonyl-[EGF-like domain protein] + UDP-N-
CA   acetyl-alpha-D-glucosamine = 3-O-(N-acetyl-beta-D-glucosaminyl-(1->3)-
CA   alpha-L-fucosyl)-L-threonyl-[EGF-like domain protein] + H(+) + UDP.
CC   -!- The enzyme, found in animals and plants, is involved in the
CC       biosynthesis of the tetrasaccharide alpha-Neu5A-(2->3)-beta-D-Gal-
CC       (1->4)-beta-D-GlcNAc-(1->3)-L-alpha-Fuc, which is attached to L-Ser
CC       or L-Thr residues within the sequence Cys-Xaa-Xaa-Gly-Gly-Ser/Thr-Cys
CC       in EGF-like domains.
CC   -!- The substrate is provided by EC 2.4.1.221.
