General annotation (Comments)

Function	Specifically catalyzes the decarboxylation of L-arginine to agmatine. Has no S-adenosylmethionine decarboxylase (AdoMetDC) activity By similarity. HAMAP MF_01298
Catalytic activity	L-arginine = agmatine + CO2. HAMAP MF_01298
Cofactor	Pyruvoyl group By similarity. HAMAP MF_01298
Pathway	Amine and polyamine biosynthesis; agmatine biosynthesis; agmatine from L-arginine: step 1/1. HAMAP MF_01298
Subunit structure	Heterooctamer of four alpha and four beta chains arranged as a tetramer of alpha/beta heterodimers By similarity.
Post-translational modification	Is synthesized initially as an inactive proenzyme. Formation of the active enzyme involves a self-maturation process in which the active site pyruvoyl group is generated from an internal serine residue via an autocatalytic post-translational modification. Two non-identical subunits are generated from the proenzyme in this reaction, and the pyruvate is formed at the N-terminus of the alpha chain, which is derived from the carboxyl end of the proenzyme. The post-translation cleavage follows an unusual pathway, termed non-hydrolytic serinolysis, in which the side chain hydroxyl group of the serine supplies its oxygen atom to form the C-terminus of the beta chain, while the remainder of the serine residue undergoes an oxidative deamination to produce ammonia and the pyruvoyl group blocking the N-terminus of the alpha chain By similarity. HAMAP MF_01298
Sequence similarities	Belongs to the prokaryotic AdoMetDC family. Type 1 subfamily.
