| 内容記述 | New bacterial rhodopsins, a bacteriorhodopsin-like and a halorhodopsin-like protein, were identified in Haloarcula vallismortis. The genes encoding these ion pumps were cloned and sequenced. The gene encoding the putative sensory rhodopsins were also cloned. The decuced amino acid sequence of the proton-pump protein was distant from the sequences of both bacteriorhodopsin in Halobacterium and archaerhodopsins in Halorubrum, but was very similar to cruxrhodopsin-1 (94% homology) in Haloarcula, and has thus been included in the cruxrhodopsin tribe as cruxrhodopsin-3. The deduced amino acid sequence of the anion-pump protein was also close to that of a putative anion pump, cruxhalorhodopsin-1, which forms a pair with cruxrhodopsin-1. This anion-pump protein was named cruxhalorhodopsin-3 and the putative sensor protein was named cruxsensory rhodopsin-3. The degree of conservation in the amino acid sequence was discussed for the individual helices of three each rhodopsin homologs, proton pumps, anion pumps and sensors in three different genera, with respect to their functional roles.The genes of light-sensing transducer proteins were also identified from Haloarcula vallismortis, Halorubrum sodomense and Halorubrum sp. aus-1. These genes were all located upstream of the genes of corresponding sensory rhodopsins. The homology between sensory rhodopsins and that between transducer proteins were well correlated. These results strongly suggest that there were twice gene duplications of an ancestry rhodopsin gene in the course to develop into four different rhodopsin homologs in the present day species; an ancestry rhodopsin had diverged to be a pump and a sensor, and then the proton pump diverged to be two ion pumps while the sensor diverged after acquisition of a transducer gene into two sensor systems. | |||||
