General annotation (Comments)

Function

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.

Catalytic activity

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

Cofactor

Binds 2 iron ions per subunit By similarity.

Pathway

Genetic information processing; DNA replication.

Subunit structure

Heterotetramer composed of a homodimer of the large subunit BORF2 (R1) and a homodimer of the small subunit (R2). Larger multisubunit protein complex are also active, composed of (R1)n(R2)n By similarity.

Sequence similarities

Belongs to the ribonucleoside diphosphate reductase small chain family.
