| FUNCTION | Catalyzes the hydrolysis of N(2)-succinylarginine into N(2)- succinylornithine, ammonia and CO(2). |
| CATALYTIC ACTIVITY | Reaction=2 H(+) + 2 H2O + N(2)-succinyl-L-arginine = CO2 + N(2)- succinyl-L-ornithine + 2 NH4(+); Xref=Rhea:RHEA:19533, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:28938, ChEBI:CHEBI:58241, ChEBI:CHEBI:58514; EC=3.5.3.23; |
| PATHWAY | Amino-acid degradation; L-arginine degradation via AST pathway; L-glutamate and succinate from L-arginine: step 2/5. |
| SUBUNIT | Homodimer. |
| SIMILARITY | Belongs to the succinylarginine dihydrolase family. |
