CC -!- FUNCTION: Provides the precursors necessary for DNA synthesis.
CC Catalyzes the biosynthesis of deoxyribonucleotides from the
CC corresponding ribonucleotides. {ECO:0000256|PIRNR:PIRNR000355}.
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:0000256|PIRNR:PIRNR000355};
CC -!- COFACTOR:
CC Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC Evidence={ECO:0000256|PIRNR:PIRNR000355,
CC ECO:0000256|PIRSR:PIRSR000355-2};
CC Note=Binds 2 iron ions per subunit. {ECO:0000256|PIRNR:PIRNR000355,
CC ECO:0000256|PIRSR:PIRSR000355-2};
CC -!- SIMILARITY: Belongs to the ribonucleoside diphosphate reductase small
CC chain family. {ECO:0000256|ARBA:ARBA00009303,
CC ECO:0000256|PIRNR:PIRNR000355}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
