ID   2.1.3.11
DE   N-succinylornithine carbamoyltransferase.
AN   N-succinyl-L-ornithine transcarbamylase.
AN   SOTCase.
AN   succinylornithine transcarbamylase.
CA   carbamoyl phosphate + N(2)-succinyl-L-ornithine = H(+) + N(2)-succinyl-L-
CA   citrulline + phosphate.
CC   -!- Specific for N-succinyl-L-ornithine and cannot use either L-ornithine
CC       (see EC 2.1.3.3) or N-acetyl-L-ornithine (see EC 2.1.3.9) as
CC       substrate.
CC   -!- However, a single amino-acid substitution (Pro90Glu) is sufficient to
CC       switch the enzyme to one that uses N-acetyl-L-ornithine as substrate.
CC   -!- It is essential for de novo arginine biosynthesis in the obligate
CC       anaerobe Bacteroides fragilis, suggesting that this organism uses an
CC       alternative pathway for synthesizing arginine.
