CC   -!- FUNCTION: Catalyzes the hydrolysis of N(2)-succinylarginine into N(2)-
CC       succinylornithine, ammonia and CO(2). {ECO:0000255|HAMAP-
CC       Rule:MF_01172}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 H(+) + 2 H2O + N(2)-succinyl-L-arginine = CO2 + N(2)-
CC         succinyl-L-ornithine + 2 NH4(+); Xref=Rhea:RHEA:19533,

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01172};
CC   -!- PATHWAY: Amino-acid degradation; L-arginine degradation via AST
CC       pathway; L-glutamate and succinate from L-arginine: step 2/5.
CC       {ECO:0000255|HAMAP-Rule:MF_01172}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01172}.
CC   -!- SIMILARITY: Belongs to the succinylarginine dihydrolase family.
CC       {ECO:0000255|HAMAP-Rule:MF_01172}.
