CC   -!- FUNCTION: Phosphorylates 5-hydroxymethyluracil (5hmdU) into 5-
CC       phosphomethyl-2'-deoxyuridine (5- PmdU) on DNA as a step in the pathway
CC       leading to thymidine hypermodifications in the viral genome
CC       (PubMed:34522950). The phosphate is added internally to the DNA polymer
CC       (PubMed:34522950). As a final result of the pathway of
CC       hypermodification, 5-aminoethoxy-2'-deoxymethyluridine (5-NeOmdU)
CC       substitutes for about 40% of the thymidines in the viral DNA
CC       (PubMed:34522950, PubMed:29555775). These modifications probably
CC       prevent degradation of viral genome by the host restriction-
CC       modification antiviral defense system (PubMed:34522950).
