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[1].

Classification and nomenclature

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

Examples

• Aromatic-L-amino-acid decarboxylase
• Glutamate decarboxylase
• Ornithine decarboxylase
• Pyruvate decarboxylase
• RuBisCO
• Uridine monophosphate synthetase
• Uroporphyrinogen III decarboxylase
