Alpha-1,3-Galactosyltransferase (GTB)

Alpha-1,3-Galactosyltransferase (GTB) (alpha 1,3GT) is responsible for catalyzing the synthesis of the α-galactose (α-Gal) epitope, known as a xenoantigen. This enzyme facilitates the transfer of galactose from UDP-Gal to either type 1 or type 2 αFuc1→2βGal-R (H) -terminating acceptors [1].
