General annotation (Comments)

Function

Cleaves a variety of phosphodiester and phosphosulfate bonds including deoxynucleotides, nucleotide sugars, and NAD By similarity.

Catalytic activity

Hydrolytically removes 5'-nucleotides successively from the 3'-hydroxy termini of 3'-hydroxy-terminated oligonucleotides.

A dinucleotide + H2O = 2 mononucleotides.

Cofactor

Binds 2 divalent metal cations per subunit Probable.

Enzyme regulation

At low concentrations of ATP, a phosphorylated active site intermediate is formed which inhibits further ATP hydrolysis.

Subcellular location

Membrane; Single-pass type II membrane protein Potential. Secreted By similarity. Note: Located to the apical surface in intestinal and kidney epithelial cells. Located to the cell surface of basophils, and to the apical plasma membrane of bile duct cells. Secreted in serum, and in lumen of epithelial cells By similarity.

Post-translational modification

N-glycosylation is necessary for correct trafficking to the apical surface, but is not the apical targeting signal By similarity.

It has been suggested that the active SMB domain may be permitted considerable disulfide bond heterogeneity or variability, thus two alternate disulfide patterns based on 3D structures are described with 1 disulfide bond conserved in both.

Sequence similarities

Belongs to the nucleotide pyrophosphatase/phosphodiesterase family.

Contains 2 SMB (somatomedin-B) domains.
