Superiority:

Heparinase II cleaves, via an elimination mechanism, sulfated polysaccharides chains containing 1-4 linkages between hexosamines and uronic acid residues (both iduronic and glucuronic acid residues). The reaction yields oligosaccharide products (mainly disaccharides) containing unsaturated uronic acids, which can be detected by UV spectroscopy at 232 nm. The enzyme cleaves both heparin and heparan sulfate, with the heparan sulfate acvitity being about twice as high as the heparin activity.
