Suppressor mutation analysis of the sensory rhodopsin I-transducer complex: insights into the color-sensing mechanism.

Journal of bacteriology - 1 Apr 1998

Jung K H, Spudich J L

Abstract excerpt

The molecular complex containing the phototaxis receptor sensory rhodopsin I (SRI) and transducer protein HtrI (halobacterial transducer for SRI) mediates color-sensitive phototaxis responses in the archaeon Halobacterium salinarum. One-photon excitation of the complex by orange light elicits att...
