Discovered the sulfate ion transporter “SyHR” that works with light, found that it has functions unprecedented so far

April 27(Thu), 2017

Akiko Niho, a Senior Undergraduate at Faculty of Pharmaceutical Sciences, Okayama University, Yuki Sudo, Professor at Division of Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, and Marie Kurihara, a Graduate Student at the division, in collaboration with Susumu Yoshizawa, Associate Professor at Atmosphere and Ocean Research Institute, The University of Tokyo, Yasuhisa Mizutani, Professor at Department of Chemistry, Graduate School of Science, Osaka University, and Tahei Tahara, Chief Scientist at the Institute of Physical and Chemical Research (RIKEN) have discovered a light-driven sulfate ion transporter, SyHR, and unveiled its ion binding site and ion transportation mechanism.  This study was reported in Journal of the American Chemical Society on March 29.

The study discovered light-driven sulfate ion transportation, a new function of membrane proteins, revealing how diversely light is utilized by living organisms.  This discovery would enable future researches to use light to control concentrations of sulfate ion, which is widely distributed in the bodies of living organisms, for understanding roles of sulfate ion in living organisms and developing techniques to measure sulfate ion concentrations in the environment.
