The retinylidene protein bacteriorhodopsin (BR) is a heptahelical light-dependent proton pump found in the purple membrane of the archaeon Halobacterium salinarum. We now show that when reconstituted ...

U.S. biologists have developed a model mapping the control circuit governing a bacteria named Halobacterium salinarum, which can live in extremely salty environments, and that can survive to radiation ...

It is unknown how the archaellum—the rotary propeller used by Archaea for motility—works. To further understand the molecular mechanism by which the hexameric ATPase motor protein FlaI drives rotation ...

When you go leave the Big Smoke, and you cruise along the coastal fringe, your eyes are soothed by all the greenery around you. But why are trees green? After all, if plants wanted to absorb the ...
