FunFam 23793: Laccase LAC12

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
Laccase. [EC: 1.10.3.2]
4 benzenediol + O(2) = 4 benzosemiquinone + 2 H(2)O.
  • A group of multi-copper proteins of low specificity.
  • Acts on both o- and p-quinols, and often acting also on aminophenols and phenylenediamine.
  • The semiquinone may react further either enzymically or non- enzymically.

L-ascorbate oxidase. [EC: 1.10.3.3]
4 L-ascorbate + O(2) = 4 monodehydroascorbate + 2 H(2)O.

    Nitrite reductase (NO-forming). [EC: 1.7.2.1]
    Nitric oxide + H(2)O + ferricytochrome c = nitrite + ferrocytochrome c + 2 H(+).
    • The reaction is catalyzed by two types of enzymes, found in the perimplasm of denitrifying bacteria.
    • One type comprises proteins containing multiple copper centers, the other a heme protein, cytochrome cd1.
    • Acceptors include c-type cytochromes such as cytochrome c-550 or cytochrome c-551 from Paracoccus denitrificans or Pseudomonas aeruginosa, and small blue copper proteins such as azurin and pseudoazurin.
    • Cytochrome cd1 also has oxidase and hydroxylamine reductase activities.
    • May also catalyze the reaction of EC 1.7.99.1 since this is a well- known activity of cytochrome cd1.
    • Formerly EC 1.6.6.5, EC 1.7.99.3 and EC 1.9.3.2.
