Conversion of erythrocyte membrane B antigen to H antigen produces blood type O which is universally transfusable. If efficient large-scale production of enzymatically converted red blood cells is to be achieved, then optimal conditions for deantigenation must be determined. Cell suspension assays were used to study the blood group B activity of Glycine max (soybean) α-D-galactosidase on native human erythrocytes. The enzyme readily hydrolyzed the terminal α-D-galactosyl residue of the B antigen, converting it to H antigen. Optimal conditions for the enzymatic conversion of red cells with the Glycine enzyme are described. Normal cell morphology and function were maintained under optimal conditions.
