Antarctic endolithic bacterial metagenome-assembled genomes

Bacterial assembled genomes and annotation data from the Antarctic cryptoendolithic communities collected during the XXXI (2015-16) Italian Antarctic Expedition.

The dataset consists of 4 zip archives and 1 metadata file (tab-separated format). Here is a brief summary of their contents:

• MAGs: high quality (HQ) and medium quality (MQ) bacterial metagenome assembled genomes.
• MAGs_Metadata: completeness, contamination, length, N50, GTDB classification for each MAG.
• MAGs_HQ_CDS:  translated coding sequences for each high quality MAG.
• MAGs_HQ_Annotation: EggNOG annotation files. For each high quality MAG, the following files are included:
  • eggnog.emapper.annotations: the final EggNOG annotation;
  • eggnog.emapper.hmm_hits: list of significant hits to eggNOG Orthologous Groups
  • eggnog.emapper.seed_orthologs: best match of each query within the best Orthologous Group (OG) reported in the eggnog.emapper.hmm_hits file.
• Jiangella_Antarctica: Candidatus Jiangella antarctica representative genome (UniValnordMG_2_bin.36.fa) and the extracted ribosomal RNA genes (rRNA.fasta).
• Order_MSA: protein multiple sequence alignments using the 120 GTDB bacterial marker genes. These alignments were used to estimate divergence times on orders containing at least 4 CBS, for a total of 19 orders.
• Samples_accession: table that relates to the NCBI deposition of the shotgun metagenomes, the following info are included:
  • NCBI Sequence Read Archive (SRA)
  • BioProject accession numbers
  • JGI Integrated Microbial Genomes & Microbiomes site IDs
  • N50 values
  • Metadata
