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.

Induction

Induced in response to the thiol oxidant diamide. Ref.2

Sequence similarities

Belongs to the ribonucleoside diphosphate reductase large chain family.
