The Irga6 G4-motif mutant hydrolyses GTP faster than XTP. (a) Hydrolysis of 10 mM GTP (with traces α32P-GTP) was measured in the presence of 80 μM WT or mutant Irga6 at 37°C. Samples were assayed by TLC and autoradiography. (b) Hydrolysis of 10 mM XTP was measured in the presence of 80 μM WT or mutant Irga6 at 37°C. Samples were assayed by HPLC.
