Protein attributes

Sequence length	599 AA.
Sequence status	Fragment.
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.
