Description
Catechol 1,2-Dioxygenase (EC 1.13.11.1) is a bacterial Fe(III)-dependent enzyme that catalyzes the intradiol ring cleavage of catechol to cis,cis-muconate. This reaction is a step in the cleavage pathway for aromatic pollutant degradation, converting toxic compounds into intermediates that enter central metabolism. This enzyme plays a role in bacterial bioremediation of phenolic contaminants. This infographic summarizes the enzyme's overall structure, active site, and catalytic mechanism based on structural data from PDB 1S9A and primary literature.
