Escherichia coli YfcE and related proteins, metallophosphatase domain YfcE is a manganase-dependent metallophosphatase, found in bacteria and archaea, that cleaves bis-p-nitrophenyl phosphate, thymidine 5'-monophosphate-p-nitrophenyl ester, and p-nitrophenyl phosphorylcholine, but is unable to hydrolyze 2',3 ' or 3',5' cyclic nucleic phosphodiesters, and various phosphomonoesters, including p-nitrophenyl phosphate. This family also includes the Bacilus subtilis YsnB and Methanococcus jannaschii MJ0936 proteins. This domain family belongs to the metallophosphatase (MPP) superfamily. MPPs are functionally diverse, but all share a conserved domain with an active site consisting of two metal ions (usually manganese, iron, or zinc) coordinated with octahedral geometry by a cage of histidine, aspartate, and asparagine residues. The MPP superfamily includes: Mre11/SbcD-like exonucleases, Dbr1-like RNA lariat debranching enzymes, YfcE-like phosphodiesterases, purple acid phosphatases (PAPs), YbbF-like UDP-2,3-diacylglucosamine hydrolases, and acid sphingomyelinases (ASMases). The conserved domain is a double beta-sheet sandwich with a di-metal active site made up of residues located at the C-terminal side of the sheets. This domain is thought to allow for productive metal coordination. |
