General annotation (Comments)

Function

This bifunctional enzyme catalyzes two consecutive reactions during ribonucleic acid degradation. Converts a 2',3'-cyclic nucleotide to a 3'-nucleotide and then the 3'-nucleotide to the corresponding nucleoside and phosphate By similarity.

Catalytic activity

Nucleoside 2',3'-cyclic phosphate + H2O = nucleoside 3'-phosphate.

A 3'-ribonucleotide + H2O = a ribonucleoside + phosphate.

Cofactor

Divalent cations By similarity.

Subcellular location

Periplasm By similarity.

Sequence similarities

Belongs to the 5'-nucleotidase family.
