Protein

Ribonucleoside-diphosphate reductase large subunit

Gene

RIR1

Organism
Human herpesvirus 2 (strain 333) (HHV-2) (Human herpes simplex virus 2)
Status
Reviewed-Annotation score: 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.UniRule annotation

Catalytic activityi

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

Pathwayi: DNA replication

This protein is involved in the pathway DNA replication, which is part of Genetic information processing.UniRule annotation
