Taxonomic identifier

393305 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Yersinia

Protein attributes

Sequence length	550 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Degradation of external UDP-glucose to uridine monophosphate and glucose-1-phosphate, which can then be used by the cell By similarity.
Catalytic activity	UDP-sugar + H2O = UMP + alpha-D-aldose 1-phosphate. A 5'-ribonucleotide + H2O = a ribonucleoside + phosphate.
Cofactor	Divalent cations. Most likely cobalt By similarity.
Subcellular location	Periplasm Potential.
Sequence similarities	Belongs to the 5'-nucleotidase family.
