Geometric distortions in FeV cofactor upon binding of CO. A) Stereo representation of a superposition of the CO‐bound state of FeV cofactor with the resting state (transparent). HCA: homocitrate. B) Important bond distances in the resting state of FeV cofactor. C) In the CO‐bound state, the bond lengths from Fe2 and Fe6 to the carbon of CO are substantially shorter than to S2B in the resting state, leading to a contraction of the cluster and a significant shortening of the Fe2‐Fe6 distance by 0.07 Å.
