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 ...

This enzyme belongs to the family of
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 the carboxy-lyases, which cleave carbon-carbon bonds. The
systematic name of this enzyme class is 2,5-dihydroxybenzoate carboxy-lyase (hydroquinone-forming). Other names in common use include 2,5-dihydroxybenzoate decarboxylase, and gentisate carboxy-lyase. This enzyme participates in
tyrosine metabolism.
