Chains	Enzyme Name	Description	Catalytic Residues
A, G	ribonucleoside-diphosphate reductase (class I) M-CSA #918	Ribonucleoside-diphosphate reductase (RNR) catalyses the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides using thioredoxin as a co-substrate. This entry represents the class I RNRs. Class I enzymes consist of two homodimeric proteins, R1 (alpha2), coded by the nrdA gene, and R2 (beta2), coded by nrdB. The large alpha chain harbours the catalytic site and binding sites for allosteric effectors. The small beta chain contains an oxygen-linked diferric centre and, in its active form, a stable tyrosyl free radical.
