CC   -!- FUNCTION: Ribonucleoside-diphosphate reductase holoenzyme provides the
CC       precursors necessary for viral DNA synthesis. Allows virus growth in
CC       non-dividing cells. Catalyzes the biosynthesis of deoxyribonucleotides
CC       from the corresponding ribonucleotides (By similarity). {ECO:0000250}.
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         Evidence={ECO:0000255|PROSITE-ProRule:PRU10014};
CC   -!- COFACTOR:
CC       Name=Fe cation; Xref=ChEBI:CHEBI:24875; Evidence={ECO:0000250};
CC       Note=Binds 2 iron ions per subunit. {ECO:0000250};
CC   -!- PATHWAY: Genetic information processing; DNA replication.
CC   -!- SUBUNIT: Heterodimer of a large and a small chain.
CC   -!- SIMILARITY: Belongs to the ribonucleoside diphosphate reductase small
CC       chain family. {ECO:0000305}.
