Decarboxylase is an enzyme that removes a carboxyl group from a molecule, ultimately resulting in decarboxylation. Some possible synonyms for decarboxylase include carboxy-lyase, decarboxylating enzyme, organic acid decarboxylase, and carboxylic acid decarboxylase. Other more specific types of decarboxylase enzymes may be referred to as amino acid decarboxylase, pyruvate decarboxylase, or histidine decarboxylase, depending on their substrate or function. Additionally, certain organisms such as bacteria or fungi may produce specific decarboxylases, such as ornithine decarboxylase or arginine decarboxylase. Overall, decarboxylase is a key enzyme in many metabolic pathways and has various synonyms depending on its specific type or function.
