CapA and related proteins, metallophosphatase domain; CapA is one of three membrane-associated enzymes in Bacillus anthracis that is required for synthesis of gamma-polyglutamic acid (PGA), a major component of the bacterial capsule. The YwtB and PgsA proteins of Bacillus subtilis are closely related to CapA and are also included in this alignment model. CapA 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.

Escherichia coli CpdB and related proteins, N-terminal metallophosphatase domain; CpdB is a bacterial periplasmic protein with an N-terminal metallophosphatase domain and a C-terminal 3'-nucleotidase domain. This alignment model represents the N-terminal metallophosphatase domain, which has 2',3'-cyclic phosphodiesterase activity, hydrolyzing the 2',3'-cyclic phosphates of adenosine, guanosine, cytosine and uridine to yield nucleoside and phosphate. CpdB also hydrolyzes the chromogenic substrates p-nitrophenyl phosphate (PNPP), bis(PNPP) and p-nitrophenyl phosphorylcholine (NPPC). CpdB is thought to play a scavenging role during RNA hydrolysis by converting the non-transportable nucleotides produced by RNaseI to nucleosides which can easily enter a cell for use as a carbon source. This family also includes YfkN, a Bacillus subtilis nucleotide phosphoesterase with two copies of each of the metallophosphatase and 3'-nucleotidase domains. The N-terminal metallophosphatase domain belongs to a large superfamily of distantly related metallophosphatases (MPPs) that 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).

Escherichia coli UshA and related proteins, N-terminal metallophosphatase domain; UshA is a bacterial periplasmic enzyme with UDP-sugar hydrolase and dinucleoside-polyphosphate hydrolase activities associated with its N-terminal metallophosphatase domain, and 5'-nucleotidase activity associated with its C-terminal domain. UshA has been studied in Escherichia coli where it is expressed from the ushA gene as an immature precursor and proteolytically cleaved to form a mature product upon export to the periplasm. UshA hydrolyzes many different nucleotides and nucleotide derivatives and has been shown to degrade external UDP-glucose to uridine, glucose 1-phosphate and phosphate for utilization by the cell. The N-terminal metallophosphatase domain belongs to a large superfamily of distantly related metallophosphatases (MPPs) that 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).
