Comments [?]

Function Catalyzes the hydrolysis of N(2)-succinylarginine into N(2)-succinylornithine, ammonia and CO(2).
Catalytic activity RHEA:19533: 2 H(+) + 2 H2O + N(2)-succinyl-L-arginine = CO2 + N(2)-succinyl-L-ornithine + 2 NH4(+)
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.
