Characteristics are defined in the text. Legend: +, protein is predicted to possesses the attribute; –, protein is predicted to not possess the attribute.

ORFs are from TM, T. maritima; TRQ2, Thermotoga species strain RQ2; Tpet, Thermotoga petrophila; Tnap, Thermotoga naphthophila; CTN, Thermotoga neapolitana; Tmel, Thermotoga melanesiensis; Fnod, Fervidobacterium nodosum; Tlet, Thermotoga lettingae; THA, Thermosipho africanus; Kole, Kosmotoga olearia; Pmob, Petrotoga mobilis; and Theba, Thermotogales bacterium mesG1.Ag.4.2 (Mesotoga prima). ORFs above the line are homologs of TM0476, those below the line are possible analogs of TM0476.

^‡Values of the percent β strand content were calculated utilizing the multisequence alignment programs STRAP and SCRATCH, respectively.
