From: Thermophile-specific proteins: the gene product of aq_1292 from Aquifex aeolicus is an NTPase
THEP1s contain Walker A and Walker B motifs. CLUSTALW analysis of all THEP1s. The positions of the Walker A and Walker B motifs are indicated. The shown sequences are from Archaeoglobus fulgidus (AF0814), Methanopyrus kandleri AV19 (MK0827), Methanosarcina acetivorans (MA3402), Methanothermobacter thermautotrophicus (MTH1068), Aeropyrum pernix (APE0781), Pyrococcus horikoshii (PH0792), Pyrococcus abyssi (PAB1537), Methanococcus jannaschii (MJ1559), Pyrobaculum aerophilum (PAE3292), Sulfolobus solfataricus (SSO2171), Aquifex aeolicus (aq_1292), Thermotoga maritima ( TM0036), Thermoplasma acidophilum (Ta0998), and Thermoplasma volcanium (TVN0737).
