FunFam 23083: Biphenyl dioxygenase subunit beta

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
3-phenylpropanoate dioxygenase. [EC:]
(1) 3-phenylpropanoate + NADH + O(2) = 3-(cis-5,6-dihydroxycyclohexa-1,3- dien-1-yl)propanoate + NAD(+). (2) (2E)-3-phenylprop-2-enoate + NADH + O(2) = (2E)-3-(2,3- dihydroxyphenyl)prop-2-enoate + NAD(+).
  • This enzyme catalyzes a step in the pathway of phenylpropanoid compounds degradation.
  • It catalyzes the insertion of both atoms of molecular oxygen into positions 2 and 3 of the phenyl ring of 3-phenylpropanoate or (2E)-3- phenylprop-2-enoate.

Benzene 1,2-dioxygenase. [EC:]
Benzene + NADH + O(2) = cis-cyclohexa-3,5-diene-1,2-diol + NAD(+).
  • A system, containing a reductase which is an iron-sulfur flavoprotein (FAD), an iron-sulfur oxygenase and ferredoxin.

Biphenyl 2,3-dioxygenase. [EC:]
Biphenyl + NADH + O(2) = (1S,2R)-3-phenylcyclohexa-3,5-diene-1,2-diol + NAD(+).
  • The enzyme from Burkholderia fungorum strain LB400 (previously Pseudomonas sp.) is part of a multicomponent system composed of an NADH:ferredoxin oxidoreductase (FAD cofactor), a [2Fe-2S] Rieske-type ferredoxin, and a terminal oxygenase that contains a [2Fe-2S] Rieske- type iron-sulfur cluster and a catalytic mononuclear nonheme iron center.
  • Chlorine-substituted biphenyls can also act as substrates.
  • Similar to the three-component enzyme systems EC and EC

Toluene dioxygenase. [EC:]
Toluene + NADH + O(2) = (1S,2R)-3-methylcyclohexa-3,5-diene-1,2-diol + NAD(+).
  • A system, containing a reductase which is an iron-sulfur flavoprotein (FAD), an iron-sulfur oxygenase, and a ferredoxin.
  • Some other aromatic compounds, including ethylbenzene, 4-xylene and some halogenated toluenes, are converted into the corresponding cis- dihydrodiols.

Benzoate 1,2-dioxygenase. [EC:]
Benzoate + NADH + O(2) = (1R,6S)-1,6-dihydroxycyclohexa-2,4-diene-1- carboxylate + NAD(+).
  • A system, containing a reductase which is an iron-sulfur flavoprotein (FAD), and an iron-sulfur oxygenase.
  • Formerly EC
