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 -!- 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}.
