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.
Classification and nomenclature
Carboxy-lyases are categorized under EC number 4.1.1.
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
Histidine decarboxylase
Ornithine decarboxylase
Phosphoenolpyruvate carboxylase
Pyruvate decarboxylase
RuBisCO – the only carboxylase that leads to a net fixation of carbon dioxide
Uridine monophosphate synthetase
Uroporphyrinogen III decarboxylase
enoyl-CoA carboxylases/reductases (ECRs)
