    Abstract
    Heparin, an anticoagulant drug, is biosynthesized in selected animal cells. The heparin biosynthetic enzymes mainly consist of sulfotransferases and all are integral transmembrane glycoproteins. These enzymes are generally produced in engineered Escherichia coli as without their transmembrane domains as non-glycosylated fusion proteins. In this study, we used the yeast, Komagataella pastoris, to prepare four sulfotransferases involved in heparin biosynthesis as glycoproteins. While the yields of these yeast-expressed enzymes were considerably lower than E. coli-expressed enzymes, these enzymes were secreted into the fermentation media simplifying their purification and were endotoxin free. The activities of these sulfotransferases, expressed as glycoproteins in yeast, were compared to the bacterially expressed proteins. The yeast-expressed sulfotransferase glycoproteins showed improved kinetic properties than the bacterially expressed proteins.;
