Abstract excerpt
pharaonis phoborhodopsin ( ppR, also called pharaonis sensory rhodopsin II, psRII) is a receptor for negative phototaxis in Natronomonas pharaonis. The X-ray crystallographic structure of ppR is very similar to those of the ion-pumping rhodopsins, bacteriorhodopsin (BR) and halorhodopsin (hR). However, the decay processes of the photocycle intermediates such as M and O are much slower than those of BR and hR,...
