abstract：:A glycosyltransferase was fused to the yeast cell wall protein Pir, which forms the Pir1-4 protein family and is incorporated into the cell wall by an unknown linkage to be displayed at the yeast cell surface. We first expressed the PIR1-HA-gma12+ fusion, in which gma12+ encodes alpha-1,2-galactosyltransferase from th...
