An Australian halobacterium contains a novel proton pump retinal protein: archaerhodopsin.
A bacterial strain collected from Western Australia carries all the specific features of Halobacteria, an extremely halophilic archaebacteria. This strain, Halobacterium sp. aus-1, contains a retinal protein which does differ from bacteriorhodopsin but still pumps out protons in the light. This novel proton pump is named "archaerhodopsin".
