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. Ref.1

Catalytic activity

Nucleoside 2',3'-cyclic phosphate + H2O = nucleoside 3'-phosphate. Ref.1

A 3'-ribonucleotide + H2O = a ribonucleoside + phosphate. Ref.1

Cofactor

Divalent cations By similarity.

Subcellular location

Periplasm Ref.1.

Miscellaneous

Two kinetically distinguishable active sites for the two substrates (2',3'-cyclic nucleotides and 3'-nucleotides) have been identified.

Sequence similarities

Belongs to the 5'-nucleotidase family.
