Abstract: A heparin structure with increased anticoagulant activity and method of making the same are disclosed. A heparin sample is provided and treated with a heparan sulfate sulfotransferase in an enzymatic reaction to add sulfuryl groups from a sulfuryl group source to the heparin sample, resulting in a heparin structure having above about 8% more 3-O-sulfo groups relative to wild-type bovine intestinal heparin. The added sulfuryl groups modify the heparin structure and increase the sample's binding to antithrombin III and its anticoagulant activity to be more similar and a viable alternative to porcine intestinal heparin. The modified heparin exhibits an anti-FXa activity and an anti-FIIa activity greater than about 180 U/mg, and a ratio of the anti-FXa activity to the anti-FIIa activity of about 0.9 to about 1.1, consistent with U.S. Pharmacopeia (USP) heparin activity specifications.
