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. |
| Enzyme regulation | Under complex allosteric control mediated by deoxynucleoside triphosphates and ATP binding. The type of nucleotide bound at the specificity site determines substrate preference. It seems probable that ATP makes the enzyme reduce CDP and UDP, dGTP favors ADP reduction and dTTP favors GDP reduction By similarity. |
| Pathway | |
| Subunit structure | Tetramer of two alpha and two beta subunits By similarity. |
| Post-translational modification | This protein undergoes protein self-splicing that involves 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. |
