Figure 4From: Thermophile-specific proteins: the gene product of aq_1292 from Aquifex aeolicus is an NTPaseaaTHEP1 is no NDP kinase. Autoradiography of thin-layer chromatograms showing samples containing [γ-32P]ATP after five minutes of incubation at 70°C and at different concentrations of ATP and GDP. 1 μg of purified aaTHEP1 was used for each assay in 25 μl buffer.Back to article page
