The <i>g–tensors</i>, <i>hfc–tensors</i> (A, mT), linewidths (LW, mT), and rotational θ angle (°) for the tyrosyl radical in class Ia and class Ib RNRs and the Y_D radical in photosystem II, *Inequivalent C₃ and C₅ protons, **Using XSophe (v. 1.1.4) (matrix diagonali

Note: similar results can be obtained with SimFonia software (v. 1.25) using the same g–tensors, hfc–tensors but very different line-width tensor (for the Fe reconstituted form LWx,y,z = 0.560, 0.630, 0.490, Lorentzian/Gaussian line-width = 0.63; for the Mn reconstituted form LWx,y,z = 0.570, 0.795, 0.550. Lorentzian/Gaussian line-width = 1). In B. Cereus, the sign and magnitude of the anisotropic hyperfine tensor components are taken from DFT analyses. The definition of θ is given in Figure 1B. ***The g-tenors for B. anthracis R2F are estimated values from simulations. The values in parenthesis ( ) corresponds to the tyrosyl radical in B. cereus R2F reconstituted with Mn.
