Modulation of Y [subscript 356] Photooxidation in E. Coli Class Ia Ribonucleotide Reductase by Y [subscript 731] Across the α [subscript 2] :β [subscript 2] Interface by Pizano, Arturo A., Olshansky, Lisa, Holder, Patrick, Stubbe, JoAnne, Nocera, Daniel G.

“…Substrate turnover in class Ia ribonucleotide reductase (RNR) requires reversible radical transport across two subunits over 35 Å, which occurs by a multistep proton-coupled electron-transfer mechanism. Using a photooxidant-labeled β[subscript 2] subunit of Escherichia coli class Ia RNR, we demonstrate photoinitiated oxidation of a tyrosine in an α[subscript 2]:β[subscript 2] complex, which results in substrate turnover. …”
