Carboxy-lyases, also known as decarboxylases, are carbon–carbon lyases that add or remove a carboxyl group from organic compounds. These enzymes catalyze the decarboxylation of amino acids, beta-keto acids and alpha-keto acids.
The enzyme Glucosaminate ammonia-lyase (EC 4.3.1.9) catalyzes the chemical reaction

The enzyme benzoylformate decarboxylase (EC 4.1.1.7) catalyzes the following chemical reaction:
The enzyme chorismate lyase catalyzes the first step in ubiquinone biosynthesis, the removal of pyruvate from chorismate, to yield 4-hydroxybenzoate in Escherichia coli and other Gram-negative bacteria. It belongs to the family of lyases, specifically the oxo-acid-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is chorismate pyruvate-lyase (4-hydroxybenzoate-forming). Other names in common use include CL, CPL, and UbiC.
The enzyme diaminobutyrate decarboxylase (EC 4.1.1.86) catalyzes the chemical reaction
In enzymology, a glutaconyl-CoA decarboxylase (EC 4.1.1.70) is an enzyme that catalyzes the chemical reaction
The enzyme o-pyrocatechuate decarboxylase (EC 4.1.1.46) catalyzes the chemical reaction
In enzymology, an oxalate decarboxylase (EC 4.1.1.2) is an oxalate degrading enzyme that catalyzes the chemical reaction
The enzyme threonine-phosphate decarboxylase (EC 4.1.1.81) catalyzes the chemical reaction
The enzyme 2-oxopent-4-enoate hydratase (EC 4.2.1.80) catalyzes the chemical reaction
4-Hydroxy-2-oxopentanoaic acid, also known as 4-hydroxy-2-oxovalerate, is formed by the decarboxylation of 4-oxalocrotonate by 4-oxalocrotonate decarboxylase, is degraded by 4-hydroxy-2-oxovalerate aldolase, forming acetaldehyde and pyruvate and is reversibly dehydrated by 2-oxopent-4-enoate hydratase to 2-oxopent-4-enoate.
In enzymology, a phenacrylate decarboxylase (EC 4.1.1.102) is an enzyme that catalyzes the chemical reaction
