This domain is responsible for the conversion of isochorismate, in the presence of water, to 2,3-dihydroxybenzoate and pyruvate. It shows a typical helix-sheet-helix sandwich structural architecture, with a central beta--sheet made of six parallel strands, three alpha -helices on one side and two on the other [3,4].	Domain
