Protein

Ribonucleoside-diphosphate reductase small chain

Gene

RR-2

Organism
Red sea bream iridovirus (RSIV)
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. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides (By similarity).By similarity

Catalytic activityi

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

Cofactori

Binds 2 iron ions per subunit.By similarity
