The present invention includes methods for preparing anticoagulant polysaccharides using several non-naturally occurring, engineered sulfotransferase enzymes that are designed to react with aryl sulfate compounds instead of the natural substrate, 3 '-phosphoadenosine 5 '-phosphosulfate, to facilitate sulfo group transfer to polysaccharide sulfo group acceptors. Suitable aryl sulfate compounds include, but are not limited to, p-nitrophenyl sulfate or 4-nitrocatechol sulfate. Anticoagulant polysaccharides produced by methods of the present invention comprise N-, 3-0-, 6- O-sulfated glucosamine residues and 2-0 sulfated hexuronic acid residues, have comparable anticoagulant activity compared to commercially-available anticoagulant polysaccharides, and can be utilized to form truncated anticoagulant polysaccharides having a reduced molecular weight.
