The enzyme heparin-sulfate lyase ()

catalyzes Catalysis () is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (). Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recyc ...

lyase In biochemistry, a lyase is an enzyme that catalyzes the breaking (an elimination reaction) of various chemical bonds by means other than hydrolysis (a substitution reaction) and oxidation, often forming a new double bond or a new ring structure. ...

s, specifically those carbon-oxygen lyases acting on polysaccharides. The systematic name of this enzyme class is heparin-sulfate lyase. Other names in common use include heparin-sulfate eliminase, heparitin-sulfate lyase, heparitinase I, and heparitinase II.
