Functioni

Catalytic activityi

Catechol + O2 = cis,cis-muconate.

Cofactori

Fe3+Note: Binds 1 Fe3+ ion per subunit.

Pathwayi: beta-ketoadipate pathway

This protein is involved in step 1 of the subpathway that synthesizes 5-oxo-4,5-dihydro-2-furylacetate from catechol.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Catechol 1,2-dioxygenase (catA)
  2. Muconate cycloisomerase 1 (catB)
  3. Muconolactone Delta-isomerase (catC)
This subpathway is part of the pathway beta-ketoadipate pathway, which is itself part of Aromatic compound metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 5-oxo-4,5-dihydro-2-furylacetate from catechol, the pathway beta-ketoadipate pathway and in Aromatic compound metabolism.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
