Protein attributes

Sequence length	964 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the reduction of ribonucleotides to deoxyribonucleotides. May function to provide a pool of deoxyribonucleotide precursors for DNA repair during oxygen limitation and/or for immediate growth after restoration of oxygen By similarity.
Catalytic activity	2'-deoxyribonucleoside diphosphate + thioredoxin disulfide + H2O = ribonucleoside diphosphate + thioredoxin.
Cofactor	5'-deoxyadenosylcobalamine (coenzyme B12) By similarity.
Sequence similarities	Belongs to the ribonucleoside diphosphate reductase class-2 family.
