Figure 6From: Thermophile-specific proteins: the gene product of aq_1292 from Aquifex aeolicus is an NTPaseaaTHEP1 is a thermophilic enzyme. Temperature dependence of aaTHEP1 catalyzed ATP hydrolysis. Measurements were performed at 5 μM ATP in buffer A. ATP-hydrolysis was measured in the presence of aaTHEP1 (squares) and spontaneous ATP-degradation was determined in the absence of aaTHEP1 (triangles). 0.5 μg of purified aaTHEP1 was used for each assay in 25 μl buffer.Back to article page
