Description
Globoside is a neutral glycosphingolipid in human erythrocytes and has blood-group-P-antigen activity. The enzyme requires a divalent cation for activity, with Mn2+ required for maximal activity. UDP-GalNAc is the only sugar donor that is used efficiently by the enzyme: UDP-Gal and UDP-GlcNAc result in very low enzyme activity. Lactosylceramide, globoside and gangliosides GM3 and GD3 are not substrates. For explanation of the superscripted '3' in the systematic name, see GL-5.3.4.
