Reaction: CMP-N-acetyl-β-neuraminate + 1,2-diacyl-3-β-D-galactosyl-sn-glycerol = CMP + 1,2-diacyl-3-[3-(N-acetyl-α-D-neuraminyl)-β-D-galactosyl]-sn-glycerol
Systematic name: CMP-N-acetyl-β-neuraminate:1,2-diacyl-3-β-D-galactosyl-sn-glycerol N-acetylneuraminyltransferase
Comments: The β-D-galactosyl residue of the oligosaccharide of glycoproteins may also act as acceptor.
