respectively, in the biosynthesis of the human blood group A and B trisaccharide antigens from the O(H)-acceptor substrates. These enzymes were cloned as synthetic genes and expressed in Escherichia coli, thereby generating large quantities of enzyme for donor specificity evaluations. The amino acid sequence of glycosyltransferase A only differs from glycosyltransferase B by four amino acids, and alteration
