Protein attributes
| Sequence length | 1084 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Inferred from homology. |
General annotation (Comments)
| Function | Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides By similarity. |
| Catalytic activity | 2'-deoxyribonucleoside diphosphate + thioredoxin disulfide + H2O = ribonucleoside diphosphate + thioredoxin. |
| Pathway | |
| Subunit structure | Tetramer of two alpha and two beta subunits By similarity. |
| Post-translational modification | This protein undergoes a protein self splicing that involves a post-translational excision of the intervening region (intein) followed by peptide ligation Probable. |
| Sequence similarities | Belongs to the ribonucleoside diphosphate reductase large chain family. Contains 1 DOD-type homing endonuclease domain. |
