| Research Abstract |
We developed new technique to identify the protein which specifically accumulated uranium effectively. This method uses the detection system that combined mass spectrograph with liquid chromatography using a size exclusion column. We tried to identify the proteins which accumulate uranium using this method. As a result, we made clear that about 46 kilo Daltons of protein accumulated uranium. It was also suggested that the protein did not conclude the amino acid including sulfur(methionine and cysteine).
