multifunctional 2',3'-cyclic-nucleotide 2'-phosphodiesterase/3'-nucleotidase/5'-nucleotidase.

2',3'-cyclic-nucleotide 2'-phosphodiesterase/5'- or 3'-nucleotidase, 5'-nucleotidase family [Nucleotide transport and metabolism, Defense mechanisms].

CD73 ecto-5'-nucleotidase and related proteins, N-terminal metallophosphatase domain. CD73 is a mammalian ecto-5'-nucleotidase expressed in endothelial cells and lymphocytes that catalyzes the conversion of 5'-AMP to adenosine in the final step of a pathway that generates adenosine from ATP. This pathway also includes a CD39 nucleoside triphosphate dephosphorylase that mediates the dephosphorylation of ATP to ADP and then to 5'-AMP. These enzymes all have an N-terminal metallophosphatase domain and a C-terminal 5'nucleotidase domain. 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.

Escherichia coli UshA-like family, N-terminal metallophosphatase domain. This family includes the bacterial enzyme UshA, and related enzymes including SoxB, CpdB, YhcR, and CD73. All members have a similar domain architecture which includes an N-terminal metallophosphatase domain and a C-terminal nucleotidase domain.
