There are 3 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.

Naphthalene 1,2-dioxygenase. [EC:]
Naphthalene + NADH + O(2) = (1R,2S)-1,2-dihydronaphthalene-1,2-diol + NAD(+).
  • Comprises a multicomponent system, containing a reductase that is an iron-sulfur flavoprotein (FAD; EC, an iron-sulfur oxygenase, and ferredoxin.

2,4-dinitrotoluene dioxygenase. [EC:]
2,4-dinitrotoluene + NADH + O(2) = 4-methyl-5-nitrocatechol + nitrite + NAD(+).
  • This enzyme, characterized from the bacterium Burkholderia sp. strain DNT, is a member of the naphthalene family of bacterial Rieske non- heme iron dioxygenases.
  • It comprises a multicomponent system, containing a Rieske [2Fe-2S] ferredoxin, an NADH-dependent flavoprotein reductase (EC, and an alpha-3-beta-3 oxygenase.
  • The enzyme forms a cis-dihydroxylated product that spontaneously rearranges to form a catechol with accompanying release of nitrite.
  • It does not act on nitrobenzene.
  • Cf. EC
