CMP-N-acetylneuraminate-beta-galactosamide-alpha-2,3-sialyltransferase 4 (ST3GAL4)

Catalyzes the formation of the NeuAc-alpha-2,3-Gal-beta- 1,4-GlcNAc-, and NeuAc-alpha-2,3-Gal-beta-1,3-GlcNAc- sequences found in terminal carbohydrate groups of glycoproteins and glycolipids. It can be involved in the biosynthesis of the sialyl Lewis X determinant.
