Evolution of rhodopsin ion pumps in haloarchaea [PDF]
BMC Evolutionary Biology, 2007 The type 1 (microbial) rhodopsins are a diverse group of photochemically reactive proteins that display a broad yet patchy distribution among the three domains of life. Recent work indicates that this pattern is likely the result of lateral gene transfer (LGT) of rhodopsin genes between major lineages, and even across domain boundaries.

Ancient origin of the divergent forms of leucyl-tRNA synthetases in the Halobacteriales
BMC Evolutionary Biology, 2012 Background Horizontal gene transfer (HGT) has greatly impacted the genealogical history of many lineages, particularly for prokaryotes, with genes frequently moving in and out of a line of descent.

Analysis of haloarchaeal twin-arginine translocase pathway reveals the diversity of the machineries
Heliyon, 2019 The twin-arginine translocase (Tat) pathway transports folded proteins across the plasma membrane and plays a critical role in protein transport in haloarchaea.
