Figure 2. Photoisomerization-induced steric-trigger in the SRII-HtrII complex.

Figure 2

SRII, sensory rhodopsin II; HtrII, haloarchaeal transducer for SRII. The three residues in SRII circled in red are those which, when engineered into bacteriorhodopsin, enable bacteriorhodopsin-mediated phototaxis signaling through HtrII [36]. Redrawn from reference 30.
