The enzyme diaminobutyrate decarboxylase (EC 4.1.1.86) catalyzes the chemical reaction
- L-2,4-diaminobutanoate [math]\displaystyle{ \rightleftharpoons }[/math] propane-1,3-diamine + 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 L-2,4-diaminobutanoate carboxy-lyase (propane-1,3-diamine-forming). Other names in common use include DABA DC, L-2,4-diaminobutyrate decarboxylase, and L-2,4-diaminobutanoate carboxy-lyase.
