== Function ==
[https://www.uniprot.org/uniprot/DDAH1_HUMAN DDAH1_HUMAN] Hydrolyzes N(G),N(G)-dimethyl-L-arginine (ADMA) and N(G)-monomethyl-L-arginine (MMA) which act as inhibitors of NOS. Has therefore a role in the regulation of nitric oxide generation.

== Publication Abstract from PubMed ==
N-(4-aminobutyl)-N'-(2-methoxyethyl)guanidine (8a) is as a potent inhibitor targeting the hDDAH-1 active site (Ki = 18 microM) and derived from a series of guanidine- and amidine-based inhibitors. Its non-amino acid nature leads to high selectivities towards other enzymes of the nitric oxide-modulating system. Crystallographic data of 8a-bound hDDAH-1 illuminated a unique binding mode. Together with its developed N-hydroxyguanidine prodrug 11, 8a will serve as a most widely applicable, currently available pharmacological tool to target DDAH-1-associated diseases.

Discovery of N-(4-Aminobutyl)-N'-(2-Methoxyethyl)guanidine as the First Selective, Non-Amino Acid, Catalytic Site Inhibitor of human dimethylarginine dimethylaminohydrolase-1 (hDDAH-1).,Lunk I, Litty FA, Hennig S, Vetter IR, Kotthaus J, Altmann KS, Ott G, Havemeyer A, Carrillo Garcia C, Clement B, Schade D J Med Chem. 2019 Dec 16. doi: 10.1021/acs.jmedchem.9b01230.
