CC   -!- FUNCTION: Trifunctional enzyme that possesses a bifunctional
CC       polynucleotide kinase/phosphatase activity and an ATP-dependent RNA
CC       ligase activity. May therefore play a role to evade an RNA damage-based
CC       host response. {ECO:0000269|PubMed:14747466}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 5'-end dephospho-2'-deoxyribonucleoside-DNA + ATP = a 5'-end
CC         5'-phospho-2'-deoxyribonucleoside-DNA + ADP + H(+);
