FunFam 9: Succinylornithine transaminase

There are 7 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
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.

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.

Succinyldiaminopimelate transaminase. [EC: 2.6.1.17]
N-succinyl-L-2,6-diaminoheptanedioate + 2-oxoglutarate = N-succinyl-2- L-amino-6-oxoheptanedioate + L-glutamate.

    (2626 more...)
    Alanine--glyoxylate transaminase. [EC: 2.6.1.44]
    L-alanine + glyoxylate = pyruvate + glycine.
    • With one component of the animal enzyme, 2-oxobutanoate can replace glyoxylate.
    • A second component also catalyzes the reaction of EC 2.6.1.51.

    (R)-3-amino-2-methylpropionate--pyruvate transaminase. [EC: 2.6.1.40]
    (R)-3-amino-2-methylpropanoate + pyruvate = 2-methyl-3-oxopropanoate + L-alanine.
    • The two enantiomers of the 2-methyl-3-oxopropanoate formed by the enzyme interconvert by enolization, so that this enzyme, together with EC 2.6.1.22, provide a route for interconversion of the enantiomers of 3-amino-2-methylpropanoate.
    • Formerly EC 2.6.1.61.

    Ethanolamine-phosphate phospho-lyase. [EC: 4.2.3.2]
    Ethanolamine phosphate + H(2)O = acetaldehyde + NH(3) + phosphate.
    • Also acts on D- (or L)-1-aminopropan-2-ol O-phosphate.
    • Formerly EC 4.2.99.7.

    5-phosphonooxy-L-lysine phospho-lyase. [EC: 4.2.3.134]
    (5R)-5-phosphonooxy-L-lysine + H(2)O = (S)-2-amino-6-oxohexanoate + NH(3) + phosphate.
    • Has no activity with phosphoethanolamine (cf. EC 4.2.3.2).
