Cofactor

Binds 2 iron ions per subunit By similarity.

Pathway

Genetic information processing; DNA replication.

Subunit structure

Heterodimer of a large and a small subunit.

Subcellular location

Cytoplasm.

Sequence similarities

Belongs to the ribonucleoside diphosphate reductase small chain family.
