Alternative Name(s): Protein B1Ribonucleoside-diphosphate reductase 1 R1 subunitRibonucleotide reductase 1

Relevance: Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R1 contains the binding sites for both substrates and allosteric effectors and carries out the actual reduction of the ribonucleotide. It also provides redox-active cysteines.

Reference: Two conserved tyrosine residues in protein R1 participate in an intermolecular electron transfer in ribonucleotide reductase.Ekberg M., Sahlin M., Eriksson M., Sjoberg B.M.J. Biol. Chem. 271:20655-20659(1996)

Purity: Greater than 90% as determined by SDS-PAGE.

Storage Buffer: Tris-based buffer，50% glycerol

Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
