Identification
NameRibonucleoside-diphosphate reductase small chain 2
Synonyms
  • Ribonucleotide reductase R2 subunit 2
  • Ribonucleotide reductase small subunit 2
Gene NameRNR4
Enzyme Class
Biological Properties
General FunctionInvolved in oxidoreductase activity
Specific FunctionProvides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. RNR4 is required for proper folding of RNR2 and assembly with the large subunits
