Radical transfer in E. coli ribonucleotide reductase: a NH(2)Y(731)/R(411)A-α mutant unmasks a new conformation of the pathway residue 731

Ribonucleotide reductases (RNRs) catalyze the conversion of ribonucleotides to deoxyribonucleotides in all living organisms. The catalytic cycle of E. coli RNR involves a long-range proton-coupled electron transfer (PCET) from a tyrosyl radical (Y(122)˙) in subunit β2 to a cysteine (C(439)) in the a...
