Protein

Ribonucleoside-diphosphate reductase small chain

Gene
ORF18
Organism
Varicella-zoster virus (strain Dumas) (HHV-3) (Human herpesvirus 3)
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. The N-terminal region confers antiapoptotic activity in differentiated cells such as neurons and is important for viral reactivation to increase neural survivability By similarity.

Catalytic activityi

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

Cofactori

Binds 2 iron ions per subunit By similarity.
