General annotation (Comments)

Function

Degradation of external UDP-glucose to uridine monophosphate and glucose-1-phosphate, which can then be used by the cell.

Catalytic activity

UDP-sugar + H2O = UMP + alpha-D-aldose 1-phosphate.

A 5'-ribonucleotide + H2O = a ribonucleoside + phosphate.

Cofactor

Binds 2 zinc ions per subunit.

Enzyme regulation

The activity of this protein is inhibited by an intracellular protein inhibitor.

Subunit structure

Monomer.

Subcellular location

Periplasm. Note: Exported from the cell, except a small proportion that is internally localized.

Sequence similarities

Belongs to the 5'-nucleotidase family.
