CC   -!- FUNCTION: Catalyzes the hydrolysis of N(2)-succinylarginine into
CC       N(2)-succinylornithine, ammonia and CO(2) (By similarity).
CC   -!- CATALYTIC ACTIVITY: N(2)-succinyl-L-arginine + 2 H(2)O = N(2)-
CC       succinyl-L-ornithine + 2 NH(3) + CO(2).
CC   -!- PATHWAY: Amino-acid degradation; L-arginine degradation via AST
CC       pathway; L-glutamate and succinate from L-arginine: step 2/5.
CC   -!- SUBUNIT: Homodimer (By similarity).
CC   -!- SIMILARITY: Belongs to the succinylarginine dihydrolase family.
