Enzyme Information

2.7.1.78
Polynucleotide 5'-hydroxyl-kinase.
based on mapping to UniProt Q9JLV6
ATP + 5'-dephospho-DNA = ADP + 5'-phospho-DNA.
-!- Also acts on 5'-dephospho-RNA 3'-mononucleotides.
3.1.3.32
Polynucleotide 3'-phosphatase.
based on mapping to UniProt Q9JLV6
A 3'-phosphopolynucleotide + H(2)O = a polynucleotide + phosphate.
-!- Also hydrolyzes nucleoside 2'-, 3'- and 5'-monophosphates, but only 2'- and 3'-phosphopolynucleotides.
