Halorubrum lacusprofundi is a rod-shaped, halophilic Archaeon in the family of Halorubraceae. It was first isolated from Deep Lake in Antarctica in the 1980s.[3]
Genome
Several strains of H. lacusprofundi have been discovered. The genome sequencing of the strain ACAM 32 was completed in 2008. The organism's genome consists of two circular chromosomes and a single circular plasmid. Chromosome I contains 2,735,295 base pairs encoding 2,801 genes and chromosome II contains 525,943 base pairs encoding 522 genes. The single plasmid contains 431,338 base pairs encoding 402 genes.[4] At least one strain of H. lacusprofundi (R1S1) contains a plasmid (pR1SE) that enables horizontal gene transfer, which takes place via a mechanism that uses vesicle-enclosed virus-like particles.[5][6][7]
Research
Its β-galactosidase enzyme has been extensively studied to understand how proteins function in low-temperature, high-saline environments.[8][9]
