B4GALNT1
Beta-1,4 N-acetylgalactosaminyltransferase 1 is an enzyme that in humans is encoded by the B4GALNT1 gene.
GM2 and GD2 gangliosides are sialic acid-containing glycosphingolipids. GalNAc-T is the enzyme involved in the biosynthesis of G and G glycosphingolipids. GalNAc-T catalyzes the transfer of GalNAc into G and G by a beta-1,4 linkage, resulting in the synthesis of G and G, respectively.
