Genome sequence of an extremely halophilic archaeon isolated from Permian Period halite, Salado Formation in New Mexico, USA: Halobacterium sp. strain NMX12-1.

Halobacterium sp. strain NMX12-1, an extremely halophilic Archaeon, was isolated from 250 million-year-old Salado Formation salt crystal in Carlsbad, New Mexico. Single-molecule real-time sequencing revealed a 3.2-Mbp genome with a 2.6-Mbp chromosome and five plasmids (234, 211, 119, 21, and 1.6-kbp). The GC-rich genome encodes an acidic proteome, characteristic of Haloarchaea.
