Protein
Ribonucleoside-diphosphate reductase small chain
Gene
ORF20
Organism
Ostreid herpesvirus 1 (isolate France) (OsHV-1) (Pacific oyster herpesvirus)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Ribonucleoside-diphosphate reductase holoenzyme provides the precursors necessary for viral DNA synthesis. Allows virus growth in non-dividing cells. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides By similarity.

Catalytic activityi

2'-deoxyribonucleoside diphosphate + thioredoxin disulfide + H2O = ribonucleoside diphosphate + thioredoxin.

Cofactori

Binds 2 iron ions per subunit By similarity.
