Figure 3. Mössbauer spectra of Av βS188A MoFeP reconstituted with 57Fe-enriched or natural-abundance Fe in comparison to Kp MoFeP (previously reported).

Figure 3.

. Spectra were recorded at 80 K and 54 mT. Oxidized βS188A was first reconstituted with 57Fe2+ (green trace), followed by a second oxidation and reconstitution with natural abundance Fe2+ (blue trace). The spectrum of Kp MoFeP with 57Fe-labelled P-clusters (black trace, 4.2 K, concentration unknown) is included as a comparison and adapted with permission under a Creative Commons (CC-BY 4.0) License from reference 52.
