RNR catalyzes the reduction of NDP to dNDP,requiring reversible radical transport across two homodimeric subunits(α2 and β2,forming an active α2β2 complex)over 35 (A) via multiple PCET steps through conserved aromatic amino acid residues: Y122●(→)W48?(→)Y356 in β2,across the interface to Y731(→)Y731(→)C439 in α2.
