Chain A,B,C (PEPQ_ALTSX | Q44238)

molecular function
	GO:0004063	aryldialkylphosphatase activity	Catalysis of the reaction: aryl dialkyl phosphate + H2O = dialkyl phosphate + an aryl alcohol.
	GO:0047862	diisopropyl-fluorophosphatase activity	Catalysis of the reaction: diisopropyl fluorophosphate + H(2)O = diisopropyl phosphate + 2 H(+) + hydrogen fluoride.
	GO:0016805	dipeptidase activity	Catalysis of the hydrolysis of a dipeptide.
	GO:0016787	hydrolase activity	Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0008235	metalloexopeptidase activity	Catalysis of the hydrolysis of a peptide bond not more than three residues from the N- or C-terminus of a polypeptide chain by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions.
	GO:0008237	metallopeptidase activity	Catalysis of the hydrolysis of peptide bonds by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions.
	GO:0008233	peptidase activity	Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid.
	GO:0016795	phosphoric triester hydrolase activity	Catalysis of the hydrolysis of a phosphoric triester.
	GO:0102009	proline dipeptidase activity	Catalysis of the reaction: H2O + a dipeptide with proline at the C-terminal <=> L-proline + a standard alpha amino acid.
biological process
	GO:0016311	dephosphorylation	The process of removing one or more phosphoric (ester or anhydride) residues from a molecule.
	GO:0006508	proteolysis	The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
	GO:0009636	response to toxic substance	Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a toxic stimulus.
