## TL;DR

This paper presents the draft genome sequence of a rare soil bacterium from the Sahara desert, revealing its potential to produce useful secondary metabolites.

## Contribution

The paper provides a new draft genome sequence for Actinopolyspora saharensis DSM 46666 and identifies its biosynthetic gene clusters.

## Key findings

- The genome is 4.67 Mbp in size with a G+C content of 69.5%.
- It contains 14 biosynthetic gene clusters for secondary metabolite production.
- Carbohydrate metabolism is supported by carbohydrate-active enzyme gene repertoires.

## Abstract

Actinopolyspora saharensis DSM 46666 (=H244), a rare actinomycete, was isolated from Palm grove in the Oasis of Inghid in the Mzab region of the Algerian Sahara and deposited in the German Collection of Microorganisms and Cell Cultures (DSMZ). Here, we report the draft genome sequence of strain DSM 46666, with a size of 4.67 Mbp and a G+C content of 69.5 %. Bioinformatic analysis of the genomic sequence revealed the carbohydrate-active enzyme gene repertoires involved in carbohydrate metabolism and the occurrence of 14 biosynthetic gene clusters disclosing the secondary metabolite capacity of strain DSM 46666.
