- Arginine decarboxylase
In
enzymology , an arginine decarboxylase (EC number|4.1.1.19) is anenzyme that catalyzes thechemical reaction :L-arginine agmatine + CO2
Hence, this enzyme has one substrate,
L-arginine , and two products,agmatine and CO2.This enzyme belongs to the family of
lyase s, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is L-arginine carboxy-lyase (agmatine-forming). Other names in common use include SpeA, and L-arginine carboxy-lyase. This enzyme participates inurea cycle and metabolism of amino groups andglutamate metabolism . It employs one cofactor,pyridoxal phosphate .tructural studies
As of late 2007, 5 structures have been solved for this class of enzymes, with PDB accession codes PDB link|1MT1, PDB link|1N13, PDB link|1N2M, PDB link|2NV9, and PDB link|2NVA.
