The protein ID number starting with MMP, Ta and VNG represents query protein from the genome of M. maripaludis S2, T. acidophilum and Halobacterium sp. NRC-1. * means protein is missing in the genomes of 4 Thermococci species.
Note ¹. Homologs to PAB2404 and PAB0188 are also found in Nanoarchaeum equitans Kin4-M.
Note ². Homolog to PAB1055 is also found in Dehalococcoides sp. CBDB1 and D. ethenogenes 195.
