Protein Domain : PhoD-like phosphatase, metallophosphatase domain IPR018946

Type  Domain
Description  Alkaline phosphatase D (PhoD) [ ] catalyses the reaction: phosphate monoester + H(2)O = an alcohol + phosphate. PhoD is similar to Ca(2+)-dependent phospholipase D [], which catalyses the hydrolysis of the ester bond between the phosphatidic acid and alcohol moieties of phospholipids [, ].PhoD (also known as alkaline phosphatase D/APaseD in Bacillus subtilis) is a secreted phosphodiesterase encoded by phoD of the Pho regulon in Bacillus subtilis. PhoD homologs are found in prokaryotes, eukaryotes, and archaea. PhoD contains a twin arginine (RR) motif and is transported by the Tat (Twin-arginine translocation) translocation pathway machinery (TatAyCy) [ , , , ]. Proteins containing this domain also includes the Fusarium oxysporum Fso1 protein []. PhoD 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 β-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 [ ].
