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.
Initial partial MR solution with PDB entry 2j5b, then determined experimental phases and heavy atom positions by SAD. Also used PDB entries 2cya and 2cyc to aid in model completion.
