B antigen terminal sugar
WebThe carbohydrate is built around a core of 5-13 sugars, called the H-antigen, that ends in a fucose sugar. For people with the O blood type, the story ends there. For the A and B types, however, a specific glycosyltransferase, such as the one shown here from PDB entry 3i0g , adds one more sugar to the end. For type A, this sugar is N ...
