This entry represents the C-terminal domain of mitochondrial D-glutamate cyclase, which converts D-glutamate to 5-oxo-D-proline [1]. This is a conserved domain also found in uncharacterised proteins from bacteria and archaea. Structural studies of the hypothetical protein TON_0340 from Thermococcus onnurineus revealed an active-site cavity harbouring a metal-binding site containing six invariant aspartate and glutamate residues that adopts an alpha/beta-structure [2]. Biochemical and mutational analysis show that TON_0340 is a Mn+2-dependent phosphatase [2].
