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.

Cofactor

Binds 2 iron ions per subunit By similarity.

Pathway

Genetic information processing; DNA replication.

Subunit structure

Tetramer of two alpha and two beta subunits By similarity.

Sequence similarities

Belongs to the ribonucleoside diphosphate reductase small chain family.
