FunFam 14: Adenosylmethionine-8-amino-7-oxononanoate aminotra...

There are 5 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
Putrescine--pyruvate transaminase. [EC: 2.6.1.113]
Putrescine + pyruvate = 4-aminobutanal + alanine.
  • The enzyme, studied in the bacterium Pseudomonas aeruginosa, participates in a putrescine degradation pathway.
  • Cf. EC 2.6.1.82.

Beta-alanine--pyruvate transaminase. [EC: 2.6.1.18]
L-alanine + 3-oxopropanoate = pyruvate + beta-alanine.

    4-aminobutyrate--pyruvate transaminase. [EC: 2.6.1.96]
    (1) 4-aminobutanoate + pyruvate = succinate semialdehyde + L-alanine. (2) 4-aminobutanoate + glyoxylate = succinate semialdehyde + glycine.
    • The enzyme is found in plants that do not have the 2-oxoglutarate dependent enzyme (cf. EC 2.6.1.19).
    • The reaction with pyruvate is reversible while the reaction with glyoxylate only takes place in the forward direction.

    Adenosylmethionine--8-amino-7-oxononanoate transaminase. [EC: 2.6.1.62]
    S-adenosyl-L-methionine + 8-amino-7-oxononanoate = S-adenosyl-4- methylthio-2-oxobutanoate + 7,8-diaminononanoate.
    • S-adenosylhomocysteine can also act as donor.

    Diaminobutyrate--2-oxoglutarate transaminase. [EC: 2.6.1.76]
    L-2,4-diaminobutanoate + 2-oxoglutarate = L-aspartate 4-semialdehyde + L-glutamate.
    • Differs from EC 2.6.1.46, which has pyruvate as the amino-group acceptor.
    • This is the first enzyme in the ectoine biosynthesis pathway, the other enzymes involved being EC 2.3.1.178 and EC 4.2.1.108.
