General annotation (Comments)

Catalytic activity	S-adenosyl-L-methionine = (5-deoxy-5-adenosyl)(3-aminopropyl)-methylsulfonium salt + CO2.
Cofactor	Pyruvoyl group.
Pathway	Amine and polyamine biosynthesis; S-adenosylmethioninamine biosynthesis; S-adenosylmethioninamine from S-adenosyl-L-methionine: step 1/1.
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.
Sequence similarities	Belongs to the eukaryotic AdoMetDC family.
Sequence caution	The sequence CAD41510.3 differs from that shown. Reason: Erroneous gene model prediction. The sequence EAZ14251.1 differs from that shown. Reason: Erroneous gene model prediction.
