Extended Data Fig. 4: Crystallographic view of all Ti(III)- and Eu(II)-reduced structures.
From: Metalloradical-driven enzymatic CO2 reduction by a dynamic Ni–Fe cluster
(a) Ti(III)-reduced pH 8.0 (Cint,o state). (b) Ti(III)-reduced pH 6.0 (Cred1 state). (c) Ti(III)-reduced pH 8.0 + CO2 (Cred2 state). (d) Ti(III)-reduced pH 8.0 + CO (Cint,o-CO state). (e) Ti(III)-reduced + CO2 pH jump (Cint,o-CO state). (f) Ti(III)-reduced pH 8.0 + CO2 pseudo-jump sample. (g) Ti(III)-reduced pH 8.0 + CO2 potential jump sample. (h) Eu(II)-reduced pH 8.0. (i) Eu(II)-reduced pH 8.0 + CO2. (j) Eu(II)-reduced pH 6.0 (Cint,i state). (k) Eu(II)-reduced pH 6.0 + CO (Cint,o-CO state). Sigma-A weighted 2Fo – Fc maps are contoured at 1.0 σ (blue mesh) and omit Fo – Fc maps (green mesh) are contoured at 4.0 σ for the ligands after the first round of refinements using simulated annealing without corresponding models.
