Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 2.7Å Ligands: C8E, MG, MSE Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function BTUB_ECOLI Involved in the active translocation of vitamin B12 (cyanocobalamin) across the outer membrane to the periplasmic space. It derives its energy for transport by interacting with the trans-periplasmic membrane protein TonB. Is also a receptor for bacteriophages BF23 and C1, and for A and E colicins.[HAMAP-Rule:MF_01531] Evolutionary Conservation Check, as determined by ConSurfDB.
