Metagenomic NrdJm5 sequences placed in full phylogeny

To search for sequences from metagenomics projects, we downloaded all TARA Ocean ORFs (Eren 2017, doi.org/10.6084/m9.figshare.4902917.v1 ; Delmont 2018, doi.org/10.1038/s41564-018-0176-9), all ORFs from the Human Microbiome Project (2019-01-09; HMP 2012a, doi.org/10.1038/nature11234 ; HMP 2012b, doi.org/10.1038/nature11209 ) the majority of bacterial MAGs and SAGs from IMG/MER (4910 MAGs, 2230 SAGs) plus 53 aquatic and soil metagenomes, in particular those with project names containing “virus”, “phage”, “therm” or “hot“ (see img_sags.tsv, img_metag_samples.tsv and img_mags.tsv) (Markowitz 2008, doi.org/10.1093/nar/gkm869).

Together, we downloaded a total of 250,881,638 ORFs. We used hmm profiles designed for each clan in the phylogeny to search the sequences. We found 181 sequences with a best match to the profile designed from the TV clan.
