The enzyme 5-guanidino-2-oxopentanoate decarboxylase (EC 4.1.1.75) catalyzes the chemical reaction

5-guanidino-2-oxo-pentanoate 4-guanidinobutanal + CO2

This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is 5-guanidino-2-oxo-pentanoate carboxy-lyase (4-guanidinobutanal-forming). Other names in common use include alpha-ketoarginine decarboxylase, and 2-oxo-5-guanidinopentanoate carboxy-lyase. It has 2 cofactors: thiamin diphosphate, and Divalent cation.

In biochemistry, a lyase is an enzyme that catalyzes the breaking of various chemical bonds by means other than hydrolysis and oxidation, often forming a new double bond or a new ring structure. The reverse reaction is also possible. For example, an enzyme that catalyzed this reaction would be a lyase:

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.
