Photochemical Generation of a Tryptophan Radical within the Subunit Interface of Ribonucleotide Reductase

The E. coli class Ia ribonucleotide reductase (RNR) achieves forward and reverse proton-coupled electron transfer (PCET) over a pathway of redox-active amino acids (β-Y(122) ⇌ β-Y(356) ⇌ α-Y(731) ⇌ α-Y(730) ⇌ α-C(439)) spanning ~35 Å and two subunits every time it turns over. We have developed photo...
