RC STRAIN=4444-74 {ECO:0000313|EMBL:EIQ34309.1, RC ECO:0000313|Proteomes:UP000004199}; RA Rasko D., Redman J., Daugherty S.C., Tallon L., Sadzewicz L., RA Jones K., Santana-Cruz I., Liu X.; RL Submitted (MAR-2012) to the EMBL/GenBank/DDBJ databases. 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: 2'-deoxyribonucleoside diphosphate + CC thioredoxin disulfide + H(2)O = ribonucleoside diphosphate + CC thioredoxin. {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. CC {ECO:0000256|PIRNR:PIRNR000355, ECO:0000256|PIRSR:PIRSR000355-2}; CC -!- PATHWAY: Genetic information processing; DNA replication. CC {ECO:0000256|PIRNR:PIRNR000355}. CC -!- SIMILARITY: Belongs to the ribonucleoside diphosphate reductase CC small chain family. {ECO:0000256|PIRNR:PIRNR000355}. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data. {ECO:0000313|EMBL:EIQ34309.1}.
