Publication Abstract from PubMed
A hypothetical protein TON_0340 of a Thermococcus species is a protein conserved in a variety of organisms including human. Herein, we present four different crystal structures of TON_0340, leading to the identification of an active-site cavity harboring a metal-binding site composed of six invariant aspartate and glutamate residues that coordinate one to three metal ions. Biochemical and mutational analyses involving many phosphorous compounds show that TON_0340 is a Mn2+-dependent phosphatase. Mg2+ binds to TON_0340 less tightly and activates the phosphatase activity less efficiently than Mn2+. Whereas Ca2+ and Zn2+ are able to bind to the protein, they are unable to activate its enzymatic activity. Since the active-site cavity is small and largely composed of nearly invariant stretches of 11 or 13 amino acids, the physiological substrates of TON_0340 and its homologues are likely to be a small and the same molecule. The Mn2+-bound TON_0340 structure provides a canonical model for the ubiquitously present TON_0340 homologues and lays a strong foundation for the elucidation of their substrate and biological function.
