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 and alpha-keto acids.
[1] Carboxy-lyases are categorized under EC number 4.1.1.
[2] Usually, they are named after the substrate whose decarboxylation they catalyze, for example pyruvate decarboxylase catalyzes the decarboxylation of pyruvate.
