Extended Data Fig. 3: Angle-dependent EPR spectra of CODH crystal suspensions recorded at 10 K and 1 mW microwave power, reduced with Eu(II)-DTPA or Ti(III)-EDTA.
From: Metalloradical-driven enzymatic CO2 reduction by a dynamic Ni–Fe cluster
(a) Ti(III)-reduced pH 6.0 sample. (b) Ti(III)-reduced pH 8.0 + CO2 sample. (c) Eu(II)-reduced pH 8.0 sample. (d) Eu(II)-reduced pH 8.0 + CO2 sample. (e) Eu(II)-reduced pH 6.0 sample. (f) Eu(II)-reduced pH 6.0 + CO sample. The different paramagnetic species have the following color code: Bred (dark cyan), CredΔNi (violet), Cred1 (red), Cred2 (blue) and Cred2’ (light blue). For the displayed spectra the resonator background was not subtracted and no baseline correction was performed to identify small anisotropic changes upon rotation of the sample.
