A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC

Accepted Name
N-succinylornithine carbamoyltransferase.
Alternative Name(s)
N-succinyl-L-ornithine transcarbamylase.
Succinylornithine transcarbamylase.
Reaction catalysed
Carbamoyl phosphate + N(2)-succinyl-L-ornithine <=> phosphate + N-succinyl-L-citrulline
  • Specific for N-succinyl-L-ornithine and cannot use either L-ornithine (see EC or N-acetyl-L-ornithine (see EC as substrate.
  • However, a single amino-acid substitution (Pro90Glu) is sufficient to switch the enzyme to one that uses N-acetyl-L-ornithine as substrate.
  • It is essential for de novo arginine biosynthesis in the obligate anaerobe Bacteroides fragilis, suggesting that this organism uses an alternative pathway for synthesizing arginine.
