Abstract
The Sulfolobales archaea have been found inhabiting acidic hot springs all over the world. Here, we report the 1.798-Mbp draft genome sequence of the thermoacidophilic Sulfolobales archaeon AZ1, reconstructed from the metagenome of a Mexican hot spring. Sequence-based comparisons revealed that the Sulfolobales archaeon AZ1 represents a novel candidate genus.

Summary
The Sulfolobales archaea have been found inhabiting acidic hot springs all over the world. The order Sulfolobales comprises the genera Sulfolobus, Acidianus, Metallosphaera, Stygiolobus, and Sulfurisphaera [3,4,5,6,7]. Sulfolobus contains the highest number of sequenced strains [8,9,10,11,12,13,14,15], and until now, only one complete Acidianus genome sequence was available [16]. Metallosphaera contains three sequenced species [17, 18, 19], including “Metallosphaera yellowstonensis,” which was first described through metagenomic efforts [20]. A novel Sulfolobales archaeon has been discovered from a metagenomic study [21].
