  1. The proteins are identified by their NCBI accession number. ORF (aa): indicates length of the open reading frame in amino acids. The prevalence in other Sulfolobales species was calculated based on the all vs. all BLASTP comparison used for Fig. 1. For some proteins, more than one hit was found in certain species (See Additional file 2: Table S1). Acronyms: M.S. (Metallosphaera sedula), M.Y (Metallosphaera yellowstonensis), S.AZ1 (Sulfolobales archaeon AZ1), S.acd1 (Sulfolobales archaeon Acd1). Aa: amino acids
