# Genome sequence and methylome profile of Natrinema pallidum strain NMX15-1, a halophilic archaeon, from Permian Period halite, Carlsbad, New Mexico

## TL;DR

This paper presents the genome and methylome of a 250-million-year-old halophilic archaeon from New Mexico.

## Contribution

The study provides the first genome sequence of Natrinema pallidum from ancient Permian halite.

## Key findings

- The genome is 3.8 Mbp and includes a chromosome and three plasmids.
- The proteome is highly acidic with 3,784 proteins identified.

## Abstract

We report the 3.8-Mbp genome sequence of an extreme Haloarchaeon, Natrinema pallidum strain NMX15-1, isolated from 250-million-year-old halite samples of the Permian Period. PacBio’s long-read sequencing revealed a genome comprising a chromosome (3.5-Mbp) and three plasmids (203, 71, and 56-Kbp). The proteome is highly acidic and includes 3,784 proteins.
