==Summary==

===Protein Function ===
In the field of enzymology, a dimethylargininase, also known as a dimethylarginine dimethylaminohydrolase (DDAH), is an enzyme that catalyzes the chemical reaction: <br/>
<div align="center">N-omega,N-omega'-methyl-L-arginine + H2O ↔ dimethylamine + L-citrulline</div>
DDAH is an enzyme found in all mammalian cells. Two isoforms exist, DDAH I and DDAH II, with some differences in tissue distribution of the two isoforms. The enzyme degrades methylarginines, specifically asymmetric dimethylarginine (ADMA) and NG-monomethyl-L-arginine (MMA).<br/>
The methylarginines ADMA and MMA inhibit the production of nitric oxide synthase. As such, DDAH is important in removing methylarginines, generated by protein degradation, from accumulating and inhibiting the generation of nitric oxide. (From Wikipedia)<br/>
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. (From Uniprot)<br/>

===Cys Function & Property===
Cys276 is one of the active site of DDAH1, which act as the nucleophile group in catalyze.<br/>
