FunFam 7173: Urea amidolyase subunit 2

There are 10 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
Urea carboxylase. [EC: 6.3.4.6]
ATP + urea + HCO(3)(-) = ADP + phosphate + urea-1-carboxylate.
  • The Saccharomyces cerevisiae enzyme (but not that from green algae) also catalyzes the reaction of EC 3.5.1.54, thus bringing about the hydrolysis of urea to CO(2) and NH(3).
  • The enzyme from the prokaryotic bacterium Oleomonas sagaranensis can also use acetamide and formamide as substrates.
  • Formerly EC 3.5.1.45.

Allophanate hydrolase. [EC: 3.5.1.54]
Urea-1-carboxylate + H(2)O = 2 CO(2) + 2 NH(3).
  • Along with EC 3.5.2.15 and EC 3.5.1.84, forms part of the cyanuric- acid metabolism pathway, which degrades s-triazide herbicides, such as atrazine (2-chloro-4-(ethylamino)-6-(isopropylamino)-1,3,5- triazine), in bacteria.
  • The Saccharomyces cerevisiae enzyme (but not that from green algae) also catalyzes the reaction of EC 6.3.4.6, thus bringing about the hydrolysis of urea to CO(2) and NH(3) in the presence of ATP and bicarbonate.
  • The enzyme from Pseudomonas sp. strain ADP has a narrow substrate specificity, being unable to use the structurally analogous compounds urea, hydroxyurea or methylcarbamate as substrate.

Peptidylprolyl isomerase. [EC: 5.2.1.8]
Peptidylproline (omega=180) = peptidylproline (omega=0).
  • The first type of this enzyme found proved to be the protein cyclophilin, which binds the immunosuppressant cyclosporin A.
  • Other distinct families of the enzyme exist, one being FK-506 binding proteins (FKBP) and another that includes parvulin from Escherichia coli.
  • The three families are structurally unrelated and can be distinguished by being inhibited by cyclosporin A, FK-506 and 5-hydroxy-1,4-naphthoquinone, respectively.

Biotin carboxylase. [EC: 6.3.4.14]
ATP + biotin-[carboxyl-carrier-protein] + HCO(3)(-) = ADP + phosphate + carboxy-biotin-[carboxyl-carrier-protein].

    Acetyl-CoA carboxylase. [EC: 6.4.1.2]
    ATP + acetyl-CoA + HCO(3)(-) = ADP + phosphate + malonyl-CoA.
    • Also catalyzes transcarboxylation; the plant enzyme also carboxylates propanoyl-CoA and butanoyl-CoA.

    Propionyl-CoA carboxylase. [EC: 6.4.1.3]
    ATP + propanoyl-CoA + HCO(3)(-) = ADP + phosphate + (S)-methylmalonyl- CoA.
    • Also carboxylates butanoyl-CoA and catalyzes transcarboxylation.
    6 A0A1I9Z7N2 A0A1I9Z7N2 B0XNG4 B0XNG4 Q4WRQ1 Q4WRQ1
    2-oxoglutarate carboxylase. [EC: 6.4.1.7]
    ATP + 2-oxoglutarate + HCO(3)(-) = ADP + phosphate + oxalosuccinate.
    • It was originally thought that this enzyme was a promoting factor for the carboxylation of 2-oxoglutarate by EC 1.1.1.41, but this has since been disproved.
    • The product of the reaction is unstable and is quickly converted into isocitrate by the action of EC 1.1.1.41.

    Pyruvate carboxylase. [EC: 6.4.1.1]
    ATP + pyruvate + HCO(3)(-) = ADP + phosphate + oxaloacetate.
    • The animal enzyme requires acetyl-CoA.
    2 A0A1A7UL65 A0A1A7UL65
    Carbamoyl-phosphate synthase (glutamine-hydrolyzing). [EC: 6.3.5.5]
    2 ATP + L-glutamine + HCO(3)(-) + H(2)O = 2 ADP + phosphate + L-glutamate + carbamoyl phosphate.
    • The product carbamoyl phosphate is an intermediate in the biosynthesis of arginine and the pyrimidine nucleotides.
    • The enzyme from Escherichia coli has three separate active sites, which are connected by a molecular tunnel that is almost 100 A in length.
    • The amidotransferase domain within the small subunit of the enzyme hydrolyzes glutamine to ammonia via a thioester intermediate.
    • The ammonia migrates through the interior of the protein, where it reacts with carboxyphosphate to produce the carbamate intermediate.
    • The carboxyphosphate intermediate is formed by the phosphorylation of hydrogencarbonate by ATP at a site contained within the N-terminal half of the large subunit.
    • The carbamate intermediate is transported through the interior of the protein to a second site within the C-terminal half of the large subunit, where it is phosphorylated by another ATP to yield the final product, carbamoyl phosphate.
    • Cf. EC 6.3.4.16.
    • Formerly EC 2.7.2.9.
    2 B0VAZ4 B0VAZ4
    Methylcrotonoyl-CoA carboxylase. [EC: 6.4.1.4]
    ATP + 3-methylcrotonoyl-CoA + HCO(3)(-) = ADP + phosphate + 3-methylglutaconyl-CoA.
