LITERATURE
heparin induces the enzyme in cells, enzyme production is also upleveled by addition of N-acetyl D-glucosamine, glutaric acid, mannitol, arabinose, pyridoxine, diammonium biphosphate, ammonium nitrate, and especially by chitin, slight enhancement by L-leucine, L-glutamine, and L-histidine, overview

inducible heparinase
phosphate suppresses the enzyme production in cells, enzyme production is also reduced by potassium nitrate, maltose, mannose, and especially by sucrose, overview
