Blastp searches were carried out on proteins specific for the Crenarchaeota or its sub-groups and the results for representative species from different sub-groups of the Crenarchaeota are shown with the observed E-values. E-values greater than 1e–3 are considered insignificant hits with lack of homology to the query protein sequence.
The dashes (–) indicate that the homolog for the protein query was not detected in the BlastP searches.
Top non-Crenarchaeota hits indicate detection of species outside the Crenarchaeota that were observed to have the lowest E-value scores.
