ENZYME entry: EC 1.17.4.1

Accepted Name
Ribonucleoside-diphosphate reductase.
Alternative Name(s)
Ribonucleotide reductase.
Reaction catalysed
2'-deoxyribonucleoside diphosphate + thioredoxin disulfide + H(2)O <=> ribonucleoside diphosphate + thioredoxin
Cofactor(s)
Fe cation.
Comment(s)
  • Responsible for the de novo conversion of ribonucleoside diphosphates into deoxyribonucleoside diphosphates, which are essential for DNA synthesis and repair.
  • While the enzyme is activated by ATP, it is inhibited by dATP.
