| actinorhodopsins: proteorhodopsin-like gene sequences found predominantly in non-marine environments. | proteorhodopsins are light-energy-harvesting transmembrane proteins encoded by genes recently discovered in the surface waters of the world's oceans. metagenomic data from the global ocean sampling expedition (gos) recovered 2674 proteorhodopsin-related sequences from 51 aquatic samples. four of these samples were from non-marine environments, specifically, lake gatun within the panama canal, delaware bay and chesapeake bay and the punta cormorant lagoon in ecuador. rhodopsins related to but phy ... | 2008 | 18218036 |
