    Fumarylacetoacetate hydrolase (FAH) is essential for the degradation of aromatic amino acids as well as for the cleavage of carbon-carbon bonds in metabolites or small organic compounds. Here, the X-ray crystal structure of EaFAH, a dimeric fumarylacetoacetate hydrolase from Exiguobacterium antarcticum, was determined, and its functional properties were investigated using biochemical methods. EaFAH adopts a mixed β-sandwich roll fold with a highly flexible lid region (Val 73 -Leu 94 ), and an Mg 2+ ion is bound at the active site by coordinating to the three carboxylate oxygen atoms of Glu 124 , Glu 126 , and Asp 155 . The hydrolytic activity of EaFAH toward various substrates, including linalyl acetate was investigated using native polyacrylamide gel electrophoresis, activity staining, gel filtration, circular dichroism spectroscopy, fluorescence, and enzyme assays.
