FunFam 40772: 2-pyrone-4,6-dicarboxylic acid hydrolase

There are 2 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
2-pyrone-4,6-dicarboxylate lactonase. [EC: 3.1.1.57]
2-oxo-2H-pyran-4,6-dicarboxylate + H(2)O = (1E)-4-oxobut-1-ene-1,2,4- tricarboxylate.
  • The product is most likely the keto-form of 4-oxalmesaconate (shown).
  • It can be converted to the enol-form, 4-hydroxybuta-1,3-diene-1,2,4- trioate, either spontaneously or by EC 5.3.2.8.

4-sulfomuconolactone hydrolase. [EC: 3.1.1.92]
4-sulfomuconolactone + H(2)O = maleylacetate + sulfite.
  • The enzyme was isolated from the bacteria Hydrogenophaga intermedia and Agrobacterium radiobacter S2.
  • It catalyzes a step in the degradation of 4-sulfocatechol.
