Non-Native Radicals and Secondary Radical Transfer Pathways Observed in Mutant R2 Proteins 

FIGURE 7. Typical EPR spectra of stable RNR radicals. A. The T t122 radical in E. coli class la RNR and the Tyrl05 radical in S. typhimurium class Ib RNR. B. The Tyrl77 in mouse RNR and the Trpl77 radical in mutant mouse RNR. Inset illustotion of die coupling of p-protons to the unpaired electron at Cl a tyrosyl radical.
