<table>
[https://www.uniprot.org/uniprot/RIR4_YEAST RIR4_YEAST] Provides 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.<ref>PMID:10535923</ref>
