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

Genetic information processing; DNA replication.

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.
