Chains	Enzyme Name	Description	Catalytic Residues
A	protein disulfide oxidoreductase M-CSA #792	Deoxyribonucleotide synthesis requires the reduction of the the C2' atom of ribonucleotides. Ribonucleotide reductase (RNR) catalyses this reaction via the formation of a disulfide bond in RNR itself. To regenerate active RNR, this disulfide must be reduced; glutaredoxin (Grx) is one of the enzymes which does this.
