Protein
Ribonucleoside-diphosphate reductase large subunit
Gene
BORF2
Organism
Epstein-Barr virus (strain AG876) (HHV-4) (Human herpesvirus 4)
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, as well as reactivation from latency in infected hosts. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides By similarity.

Catalytic activityi

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