DDAH2 background information

DDAH2 is believed to hydrolyze N(G),N(G)-dimethyl-L-arginine (ADMA) and N(G)-monomethyl-L-arginine (MMA) which act as inhibitors of NOS. Therefore, it is believed to have a role in the regulation of nitric oxide generation. However, its enzymatic activity is a subject of a debate.
