DFT Calculations for Intermediate and Active States of the Diiron Center with Tryptophan or Tyrosine Radical in Escherichia coli Ribonucleotide Reductase

Class Ia ribonucleotide reductase (RNR) subunit R2 contains a diiron active site. In this paper, active site models for the intermediate X-Trp48(+·) and X-Tyr122(·), the active Fe(III)Fe(III)-Tyr122(·), and the met Fe(III)Fe(III) states of E. coli R2 are studied, using broken-symmetry density functi...
