Chain A (TCBD_PSESQ | P27099)

molecular function
	GO:0003824	catalytic activity	Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
	GO:0018850	chloromuconate cycloisomerase activity	Catalysis of the reaction: 2-chloro-2,5-dihydro-5-oxofuran-2-acetate = 3-chloro-cis,cis-muconate.
	GO:0016853	isomerase activity	Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5.
	GO:0030145	manganese ion binding	Interacting selectively and non-covalently with manganese (Mn) ions.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0018849	muconate cycloisomerase activity	Catalysis of the reaction: 2,5-dihydro-5-oxofuran-2-acetate = cis,cis-hexadienedioate.
biological process
	GO:0046300	2,4-dichlorophenoxyacetic acid catabolic process	The chemical reactions and pathways resulting in the breakdown of 2,4-dichlorophenoxyacetic acid, a chlorinated phenoxy compound which functions as a systemic herbicide and is used to control many types of broadleaf weeds.
	GO:0019439	aromatic compound catabolic process	The chemical reactions and pathways resulting in the breakdown of aromatic compounds, any substance containing an aromatic carbon ring.
	GO:0009063	cellular amino acid catabolic process	The chemical reactions and pathways resulting in the breakdown of amino acids, organic acids containing one or more amino substituents.
	GO:0008152	metabolic process	The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
