Sialyltransferases are enzymes that transfer sialic acid to nascent oligosaccharide. Each sialyltransferase is specific for a particular sugar substrate. Sialyltransferases add sialic acid to the terminal portions of the sialylated glycolipids (gangliosides) or to the N- or O-linked sugar chains of glycoproteins.

ST6 (alpha-N-acetyl-neuraminyl-2,3-beta-galactosyl-1,3)-N-acetylgalactosaminide alpha-2,6-sialyltransferase 4, also known as sialyltransferase 3C (SIAT3-C) or sialyltransferase 7D (SIAT7-D) is a sialyltransferase enzyme that in humans is encoded by the ST6GALNAC4 gene.
Alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase 1 is an enzyme that in humans is encoded by the ST6GALNAC1 gene. This enzyme adds a N-acetylneuraminic acid to an O-linked N-acetylgalactosamine (GalNAc) on a peptide/proteins with an α2-6 linkage to produce the sialyl-Tn antigen. It has been shown that the enzyme prefers threonine over serine containing GalNAc residues.
Alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase 2 is an enzyme that in humans is encoded by the ST6GALNAC2 gene.
α-N-Acetylneuraminyl-2,3-beta-galactosyl-1,3-N-acetylgalactosaminide 6-α-sialyltransferase is an enzyme with systematic name CMP-N-acetylneuraminate:N-acetyl-alpha-neuraminyl-(2->3)-beta-D-galactosyl-(1->3)- N-acetyl-D-galactosaminide galactosamine-6-alpha-N-acetylneuraminyltransferase. This enzyme catalyses the following chemical reaction
