FunFam 79317: Aminotransferase class-III family protein

There are 3 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Acetylornithine transaminase. [EC: 2.6.1.11]
N(2)-acetyl-L-ornithine + 2-oxoglutarate = N-acetyl-L-glutamate 5-semialdehyde + L-glutamate.
  • Also acts on L-ornithine and N(2)-succinyl-L-ornithine.

Succinylornithine transaminase. [EC: 2.6.1.81]
N(2)-succinyl-L-ornithine + 2-oxoglutarate = N-succinyl-L-glutamate 5-semialdehyde + L-glutamate.
  • Also acts on N(2)-acetyl-L-ornithine and L-ornithine, but more slowly.
  • In Pseudomonas aeruginosa, the arginine-inducible succinylornithine transaminase, EC 2.6.1.11 and EC 2.6.1.13 activities are catalyzed by the same enzyme, but this is not the case in all species.
  • This is the third enzyme in the arginine succinyltransferase (AST) pathway for the catabolism of arginine.
  • This pathway converts the carbon skeleton of arginine into glutamate, with the concomitant production of ammonia and conversion of succinyl-CoA into succinate and CoA.
  • The five enzymes involved in this pathway are EC 2.3.1.109, EC 3.5.3.23, EC 2.6.1.81, EC 1.2.1.71 and EC 3.5.1.96.
 1 D0HI95
Succinyldiaminopimelate transaminase. [EC: 2.6.1.17]
N-succinyl-L-2,6-diaminoheptanedioate + 2-oxoglutarate = N-succinyl-2- L-amino-6-oxoheptanedioate + L-glutamate.
