General annotation (Comments)
| Function | Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. |
| Catalytic activity | 2'-deoxyribonucleoside diphosphate + thioredoxin disulfide + H2O = ribonucleoside diphosphate + thioredoxin. |
| Cofactor | Binds 2 iron ions per subunit By similarity. |
| Pathway | |
| Subunit structure | Heterodimer of a large and a small subunit. |
| Subcellular location | |
| Sequence similarities | Belongs to the ribonucleoside diphosphate reductase small chain family. |
