| Outline of Final Research Achievements |
BCG3185c is a novel protein from M. Tuberculosis, and the protein is emerged to be a target of Agelasine D. Agelasine D is derived from Marine sponge and shows inhibition to a tubercle bacillus. In order to clarify mechanism of the inhibition, we performed purification and X-ray crystallographic analysis on BCG3185c protein. Although co-crystallization of BCG3185c and Agelasine D was extremely difficult, we succeeded to acquire structural information on BCG3185c protein without Agelasine D. Subsequently, we performed docking simulation on Agelasine D to BCG3185c, and the results suggested that several aromatic amino acids in BCG3185c could be critical for binding of Agelasine D.
While, we have been exploring other target protein for Helicyclamine A, an antibiotic for tuberculosis, and BCG2664 was identified to be a candidate applied for tuberculosis. Finally, we could establish a protocol for purification of BCG2664 protein.
