Protein

Probable ribonucleoside-diphosphate reductase small subunit 048L

Gene

IIV3-048L

Organism
Invertebrate iridescent virus 3 (IIV-3) (Mosquito iridescent virus)
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. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides (By similarity).By similarity

Catalytic activityi

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

Cofactori

Fe cationBy similarityNote: Binds 2 iron ions per subunit.By similarity
