  Domain Name: MPP_UshA_N
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 derivitives 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). 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 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.
No pairwise interactions are available for this conserved domain.

  CALCIFICATION OF JOINTS AND ARTERIES


Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
