CC -!- FUNCTION: Specifically catalyzes the decarboxylation of L-arginine to
CC agmatine. Has no S-adenosylmethionine decarboxylase (AdoMetDC)
CC activity. {ECO:0000255|HAMAP-Rule:MF_01298}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + L-arginine = agmatine + CO2; Xref=Rhea:RHEA:17641,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:32682,
CC ChEBI:CHEBI:58145; EC=4.1.1.19; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01298};
CC -!- COFACTOR:
CC Name=pyruvate; Xref=ChEBI:CHEBI:15361;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01298};
CC Note=Binds 1 pyruvoyl group covalently per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_01298};
CC -!- PATHWAY: Amine and polyamine biosynthesis; agmatine biosynthesis;
CC agmatine from L-arginine: step 1/1. {ECO:0000255|HAMAP-Rule:MF_01298}.
CC -!- SUBUNIT: Heterooctamer of four alpha and four beta chains arranged as a
CC tetramer of alpha/beta heterodimers. {ECO:0000255|HAMAP-Rule:MF_01298}.
CC -!- PTM: Is synthesized initially as an inactive proenzyme. Formation of
CC the active enzyme involves a self-maturation process in which the
CC active site pyruvoyl group is generated from an internal serine residue
CC via an autocatalytic post-translational modification. Two non-identical
CC subunits are generated from the proenzyme in this reaction, and the
CC pyruvate is formed at the N-terminus of the alpha chain, which is
CC derived from the carboxyl end of the proenzyme. The post-translation
CC cleavage follows an unusual pathway, termed non-hydrolytic serinolysis,
CC in which the side chain hydroxyl group of the serine supplies its
CC oxygen atom to form the C-terminus of the beta chain, while the
CC remainder of the serine residue undergoes an oxidative deamination to
CC produce ammonia and the pyruvoyl group blocking the N-terminus of the
CC alpha chain. {ECO:0000255|HAMAP-Rule:MF_01298}.
CC -!- SIMILARITY: Belongs to the prokaryotic AdoMetDC family. Type 1
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01298}.
