FunctionDDAH1_BOVIN 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. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedDimethylarginine dimethylaminohydrolase (DDAH) is involved in the regulation of nitric oxide synthase (NOS) by metabolizing the free endogenous arginine derivatives N(omega)-methyl-L-arginine (MMA) and N(omega),N(omega)-dimethyl-L-arginine (ADMA), which are competitive inhibitors of NOS. Here, we present high-resolution crystal structures of DDAH isoform 1 (DDAH-1) isolated from bovine brain in complex with different inhibitors, including S-nitroso-L-homocysteine and Zn2+, a regulator of this mammalian enzyme. The structure of DDAH-1 consists of a propeller-like fold similar to other arginine-modifying enzymes and a flexible loop, which adopts different conformations and acts as a lid at the entrance of the active site. The orientation and interaction mode of inhibitors in the active site give insight into the regulation and the molecular mechanism of the enzyme. The presented structures provide a basis for the structure-based development of specific DDAH-1 inhibitors that might be useful in the therapeutic treatment of NOS dysfunction-related diseases.
