Bond length of the heme-proximal histidine ligand [A and B molecules are shown in (a) and (b), respectively] derived from the DtpAa SFX diffraction data collected at Cristallina-MX in June and September 2023 as a function of the step size within (left) and between (right) scan lines. The plotted values are listed in Supplementary Table S3. Data from the small unit-cell crystals (a = 73.4, b = 68.8, c = 75.9 Å, β = 105.7°) are depicted by filled symbols (black circles) and the large unit-cell data (a = 75.0, b = 68.4, c = 77.6 Å, β = 107.6°) by open symbols (black circles). Error bars were derived by bootstrapping.
