In enzymology, a galactoside 2-alpha-L-fucosyltransferase (EC 2.4.1.69) is an enzyme that catalyzes the chemical reaction
- GDP-beta-L-fucose + beta-D-galactosyl-R GDP + alpha-L-fucosyl-1,2-beta-D-galactosyl-R
Thus, the two substrates of this enzyme are GDP-beta-L-fucose and beta-D-galactosyl-R, whereas its two products are GDP and alpha-L-fucosyl-1,2-beta-D-galactosyl-R.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. This enzyme participates in 4 metabolic pathways: glycosphingolipid biosynthesis - lactoseries, glycosphingolipid biosynthesis - neo-lactoseries, glycosphingolipid biosynthesis - globoseries, and glycan structures - biosynthesis 2.
