Enzyme Information

3.1.3.5
5'-nucleotidase.
based on mapping to UniProt Q9D020
A 5'-ribonucleotide + H(2)O = a ribonucleoside + phosphate.
-!- Wide specificity for 5'-nucleotides.
3.1.3.91
7-methylguanosine nucleotidase.
based on mapping to UniProt Q9D020
(1) N(7)-methyl-GMP + H(2)O = N(7)-methyl-guanosine + phosphate. (2) CMP + H(2)O = cytidine + phosphate.
-!- The enzyme also has low activity with N(7)-methyl-GDP, producing N(7)-methyl-GMP. -!- Does not accept AMP or GMP, and has low activity with UMP.
