The enzyme aconitate decarboxylase (EC 4.1.1.6) catalyzes the chemical reaction
- cis-aconitate [math]\displaystyle{ \rightleftharpoons }[/math] itaconate + CO2
Hence, this enzyme has one substrate, cis-aconitate, and two products, itaconate and CO2.
This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is cis-aconitate carboxy-lyase (itaconate-forming). Other names in common use include cis-aconitic decarboxylase, CAD, cis-aconitate carboxy-lyase, and cis-aconitate carboxy-lyase. This enzyme participates in c5-branched dibasic acid metabolism.
