"Aquatic ecosystems play a major role in the conversion of light energy into chemical energy, principally via chlorophyll-based photosynthesis (refs 1, 2). Other light-harvesting mechanisms include the light-driven proton pump bacteriorhodopsin, used by halobacteria living in salt ponds to supplement respiration (ref 3). In 2000, a novel light-driven proton pump, proteorhodopsin (PR), was discovered (ref 4). The world’s oceans contain an estimated 10^28 PR-expressing bacteria, placing them among the most prevalent organisms on Earth (primary sources)." |
