Research Abstract	Goadsporin is an antibiotic which inhibits the growth of actinomycetes. As the molecular target of goadsporin was proposed to be unprecedented, it was expected that the characterization of the mechanism of goadsporin action would lead to the development of drugs which possessed novel mechanism of action. This study aimed to reveal the mechanism of goadsporin action. Ffh, a possible target of goadsporin was successfully expressed as a soluble protein in Escherichia coli. GodI, a goadsporin-resistant Ffh homologue was also obtained as a recombinant protein. Using recombinant Ffh and GodI, crystallization experiments were performed. As a result, microcrystal-like objects were obtained in some conditions.
