The crystal structure of human tyrosylprotein sulfotransferase was determined in the form of a complex with a target protein, and the mechanism of its action was elucidated for the first time in the world by a joint research group including Yoshimitsu Kakuta (associate professor) from the Graduate School of the Faculty of Agriculture, Kyushu University, and Masahito Suiko (professor) and Yoichi Sakakibara (professor) from the Faculty of Agriculture, the University of Miyazaki. This sulfotransferase acts to attach a marker (sulfate group) to various types of protein. The sulfate group attached to the protein is not only related to various types of biological defense mechanism but also used in viral invasion into a human cell. The elucidated sulfate-group attachment mechanism is expected to contribute to the development of new medicines including antiviral agents. The results of this research were published in Nature Communications, an offshoot of the international scientific journal Nature, on 12 March 2013. Publication: |
