RcnR is a transcription factor that regulates the homeostasis of cobalt and nickel in bacterial cells. Escherichia coli RcnR was crystallized with DNA that encompasses the DNA-binding site. X-ray diffraction data were collected to 2.9Å resolution. The crystal belonged to space group P6122 or P6522, with unit-cell parameters a = b = 73.59, c = 157.66Å, α = β = 90, γ = 120°.

Funding Information:
The final X-ray diffraction data were collected at Argonne National Laboratory, Sector 23, GM/CA at the Advanced Photon Source. Argonne is operated by UChicago Argonne LLC for the US Department of Energy, Office of Biological and Environmental Research under contract DE-AC02-06CH11357. GM/CA@APS has been funded in whole or in part with Federal funds from the National Cancer Institute (ACB-12002) and the National Institute of General Medical Sciences (AGM-12006). The EIGER 16M detector was funded by an NIH–Office of Research Infrastructure Programs High-End Instrumentation Grant (S10 OD012289). We thank Nagarajan Venugopalan at APS 23-ID-B for the help during data collection. Computational resources and software were made available by the Minnesota Supercomputing Institute. Preliminary X-ray diffraction data were collected at the Kahlert Structural Biology Laboratory, University of Minnesota, and we thank Ed Hoeffner for his technical support. We also thank Dr Hideki Aihara and Dr Ke Shi for valuable discussions.
