Research Abstract	Metals are essential elements to catalyze important reactions for maintaining life activity. In the previous studies, we found that sulfur-oxidizing chemosynthetic bacterium produced aluminum (Al)-binding proteins. Therefore, the aim of this study is to identify novel Al-binding proteins from the bacterium. In the 1st year, I established the method to obtain high amount of cells and their proteins. In the 2nd year, we tried to isolation of Al-binding proteins from the bacterium. Now, we have been determining the amino acid sequence of 4 candidates.
