1A1-U05 An optical device powered by biological molecular motors : Design of molecular photoswitch by protein engineering approach(MEMS and Nano-Technology)

Abstract

Biological molecular motors, motor proteins have large potential for engineering application. We previously reported an optical device driven by motor protein that is designed by mimicking a molecular system of fish melanophore. This device, however, does not equip a regulating system, so that reaction is one-way, not reversible. To improve this, in this paper, we propose and develop a molecular photoswitch by fusing the photo-sensor protein LOVJa and motor protein.
