Ribonucleoside-diphosphate reductase large subunit

Gene

RIR1

Organism

Status
Reviewed-Annotation score: -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). The N-terminal region confers antiapoptotic activity in differentiated cells such as neurons and is important for viral reactivation to increase neural survivability.UniRule annotation1 Publication

Catalytic activityi

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