Find PDB structures and Computed Structure Models (CSM) by combining queries from tools in this suite: Attribute Search, Sequence Similarity, Sequence Motif, 3D Similarity, and 3D Motif with 'AND' logic.
The starting model for molecular replacement was VNG0258H/RosR (from KCl; PDB code 6FDH) and a DNA model derived from Mycobacterium tuberculosis MosR (PDB code 4FX4) but with the S1 sequence.

The complex crystallized from a buffer containing 20 mM HEPES, pH 7, 2 M KCl and 0.02% azide.
Crystals grown with S1 (DNA/hsRosR ratio = 1.46) appeared after 3 days in wells containing 2.77 M (NH4)2SO4, 50 mM MnCl2 and 0.02% azide.
