FunFam 81189: Probable serine acetyltransferase 3

There are 6 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
Serine O-acetyltransferase. [EC: 2.3.1.30]
Acetyl-CoA + L-serine = CoA + O-acetyl-L-serine.

    N-succinylarginine dihydrolase. [EC: 3.5.3.23]
    N(2)-succinyl-L-arginine + 2 H(2)O = N(2)-succinyl-L-ornithine + 2 NH(3) + CO(2).
    • Arginine, N(2)-acetylarginine and N(2)-glutamylarginine do not act as substrates.
    • The second 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 2.6.1.11, EC 1.2.1.71 and EC 3.5.1.96.

    Glycerol-3-phosphate dehydrogenase (NAD(P)(+)). [EC: 1.1.1.94]
    sn-glycerol 3-phosphate + NAD(P)(+) = glycerone phosphate + NAD(P)H.
    • The enzyme from Escherichia coli shows specificity for the B side of NADPH.

    Glucosamine N-acetyltransferase. [EC: 2.3.1.3]
    Acetyl-CoA + D-glucosamine = CoA + N-acetyl-D-glucosamine.
      2 A0A0P0US64 A0A0P0US64
      Cysteine--tRNA ligase. [EC: 6.1.1.16]
      ATP + L-cysteine + tRNA(Cys) = AMP + diphosphate + L-cysteinyl-tRNA(Cys).
        2 A0A0F3GKI2 A0A0F3GKI2
        Tetrahydrodipicolinate N-acetyltransferase. [EC: 2.3.1.89]
        Acetyl-CoA + (S)-2,3,4,5-tetrahydropyridine-2,6-dicarboxylate + H(2)O = CoA + L-2-acetamido-6-oxoheptanedioate.
