<p><strong>INTRODUCTION</strong></p>
<p>AMPSphere is a comprehensive catalog of antimicrobial peptides predicted using Macrel (DOI: <a href="https://peerj.com/articles/10555/">10.7717/peerj.10555</a>) from 63,410 public metagenomes, <a href="http://progenomes.embl.de/">ProGenomes v2.2 database</a> (82,400 high-quality microbial genomes), and c.a. 4k non-whitelisted microbial genomes from NCBI.</p>
<p> </p>
<p><strong>GENERATION</strong></p>
<p>Peptides were predicted using Macrel. Singleton peptides were removed, except those with a direct hit to the <a href="http://dramp.cpu-bioinfor.org/">DRAMP database</a>.</p>
<p>Redundant peptides were hierarchically clustered using CD-HIT (version 4.6) at 100%, 85%, 75%, and 50% of amino acid identity (and 90% of overlap of the shorter peptide). The obtained clusters were sorted by decrescent size and<br>
numbered as families. Each level of clustering was called SPHERE and was used to understand the AMPs' structure accordingly to their orthology.</p>
<p>Nucleotide sequences from the most frequent variants per AMP also were included in this version of AMPSphere.</p>
<p> </p>
<p><strong>STATISTICS</strong></p>
<p>AMPSphere v.2021-03 contains 863,498 sequences (avg length: 36 amino acids, range 8-98). DRAMP database was used to find confirmed sequences with strict homology to reference. This approach showed that 2,488 peptides were previously confirmed in our dataset.</p>
<p> </p>
<p><strong>IDENTIFIERS</strong></p>
<p>Peptides are named:</p>
<pre><code>>AMP10.XXX_XXX</code></pre>
<p>Where `XXX_XXX` is a unique numerical identifier (starting at zero). Numbers were assigned in order of increasing<br>
number of copies. So that the lower the number, the higher the number of copies of that peptide was present in the input data.</p>
<p>Annotations were also provided as separated fields in the fasta file, containing their:</p>
<p>- SPHERE families at level 4 (corresponding to hierarchically obtained clusters using 100%, 85%, and 75% of identity with a minimum overlap of 90% of the shorter gene).</p>
<p>Example of the header:</p>
<pre><code>>AMP10.000_000 | SPHERE-III.001_396</code></pre>
<p> </p>
<p><strong>VERSION</strong></p>
<p>This version <strong>v.2021-03</strong> brings the validated SPHERE families. Using the families from level III, containing 8 sequences or more, we calculated the alignments and trees in Newick format, which were included in this version too. No major changes were made in the other files besides the naming.</p>
