Definition of taxonomy
The search for taxonomic rank was carried out automatically using the Selenium WebDriver library (Python 3.6;https://github.com/SeleniumHQ/selenium). The databases contain Hsp60 sequences of 19 phyla that were sorted by taxonomic rank using the NCBI Taxonomy Database (https://www.ncbi.nlm.nih.gov/taxonomy) (Table 1). Some of the sequences belonging to the super kingdom Viruses have not been identified by phylum.
