Protein

Ribonucleoside-diphosphate reductase large subunit

Gene

BORF2

Organism
Epstein-Barr virus (strain B95-8) (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).By similarity

Catalytic activityi

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