Chain A,B,C,D (HPCE_ECOLX | P37352)

molecular function
	GO:0008704	5-carboxymethyl-2-hydroxymuconate delta-isomerase activity	Catalysis of the reaction: 5-carboxymethyl-2-hydroxymuconate = 5-carboxy-2-oxohept-3-enedioate.
	GO:0018800	5-oxopent-3-ene-1,2,5-tricarboxylate decarboxylase activity	Catalysis of the reaction: 5-oxopent-3-ene-1,2,5-tricarboxylate = 2-oxohept-3-enedioate + CO2.
	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: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:0016829	lyase activity	Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
biological process
	GO:1901023	4-hydroxyphenylacetate catabolic process	The chemical reactions and pathways resulting in the breakdown of 4-hydroxyphenylacetate.
	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: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.
