CC   -!- FUNCTION: Ribonucleoside-diphosphate reductase holoenzyme provides the
CC       precursors necessary for viral DNA synthesis. Allows virus growth in
CC       non-dividing cells, as well as reactivation from latency in infected
CC       hosts. Catalyzes the biosynthesis of deoxyribonucleotides from the
CC       corresponding ribonucleotides. {ECO:0000255|HAMAP-Rule:MF_04028}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[thioredoxin]-disulfide + a 2'-deoxyribonucleoside 5'-
CC         diphosphate + H2O = [thioredoxin]-dithiol + a ribonucleoside 5'-
CC         diphosphate; Xref=Rhea:RHEA:23252, Rhea:RHEA-COMP:10698, Rhea:RHEA-
CC         COMP:10700, ChEBI:CHEBI:15377, ChEBI:CHEBI:29950, ChEBI:CHEBI:50058,
CC         ChEBI:CHEBI:57930, ChEBI:CHEBI:73316; EC=1.17.4.1;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_04028};
CC   -!- COFACTOR:
CC       Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_04028};
CC   -!- PATHWAY: Genetic information processing; DNA replication.
CC       {ECO:0000255|HAMAP-Rule:MF_04028}.
CC   -!- SUBUNIT: Heterotetramer composed of a homodimer of the large subunit
CC       (R1) and a homodimer of the small subunit (R2). Larger multisubunit
CC       protein complex are also active, composed of (R1)n(R2)n.
CC       {ECO:0000255|HAMAP-Rule:MF_04028}.
CC   -!- INTERACTION:
CC       Q4JQV7; Q4JQV2: ORF23; NbExp=3; IntAct=EBI-2532450, EBI-2532547;
CC       Q4JQV7; Q4JQU9: ORF26; NbExp=3; IntAct=EBI-2532450, EBI-2532467;
CC   -!- SUBCELLULAR LOCATION: Host membrane {ECO:0000255|HAMAP-Rule:MF_04028};
CC       Single-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_04028}.
CC   -!- SIMILARITY: Belongs to the ribonucleoside diphosphate reductase small
CC       chain family. {ECO:0000255|HAMAP-Rule:MF_04028}.
