Figure 5: X-ray photon-induced dehalogenation.
From: Cobamide-mediated enzymatic reductive dehalogenation via long-range electron transfer

Time-series of a crystal soaked in 4-iodophenol under non-reducing conditions, exposed to a 50 μm diameter synchrotron X-ray beam (approximately 1011 photons s−1, λ=1.4 Å) at 100 K. Both 2Fo-Fc (blue, 1 σ) and iodine-anomalous difference (purple, 5 σ) electron density, shown for the substituent, successively shifted away from C4 into the cavity around Lys64, Glu92 and Tyr382.
