WebAug 17, 1999 · An aliquot (20 μl) was diluted 1:2 with assay buffer that contained carbachol and [γ-32 P]GTP (300–700 nM), and the mixture was incubated for 1 min (10°C) or 6 s (30°C) to initiate steady-state hydrolysis and allow accumulation of G q –[γ-32 P]GTP without excessive production of background [32 P]P i. WebMar 25, 2024 · However, when we included the mutant in a multiple turnover GTP hydrolysis assay (Figure 5F) in which both Rag subunits were forced to bind GTP simultaneously, we observed a striking difference: the Δ165 mutant failed to stimulate GTP hydrolysis by the Rag GTPase heterodimer (Figures 5G and 5H). This result indicates …
GTPases are a large family of hydrolase enzymes that bind to the nucleotide guanosine triphosphate (GTP) and hydrolyze it to guanosine diphosphate (GDP). The GTP binding and hydrolysis takes place in the highly conserved P-loop "G domain", a protein domain common to many GTPases. WebThe measurement of GTP hydrolysis in vitro can therefore provide information on the intrinsic activity of the small GTPase (e.g., mutated GTPase activity) as well as help define GAP specificity. Current methods to measure GTP hydrolysis in vitro utilise either radioactivity-based filter-binding assays or measurements of GDP:GTP:P (i) ratios by ...
WebRho-related GTP binding proteins Rho A, B, and C (UniProt: P61586, P62745, and P08134, respectively) are encoded by the RHOA, RHOB, and RHOC genes (Gene ID: 387, 388, and 389, respectively) in human. Rho GTPases that belong to the Ras superfamily of small GTPases are molecular switches cycling between a GDP-bound off- and a GTP-bound … WebJun 8, 2015 · We note that, in contrast to the GTP hydrolysis assay reported in Fig. 3A, technical challenges associated with phosphoenriching P∼EF-Tu in the quantities required for this experiment prevented us from testing whether dephosphorylation of P∼EF-Tu by PrpC could reverse the inhibitory effect that phosphorylation of EF-Tu has on the rate of ...
WebMay 5, 2004 · The single-turnover rate of GTP hydrolysis from Gα i1 ·[γ 32 P]GTP is measured by the 32 P i released after acid-quench of the reaction at various time points after addition of Mg 2+ (Fig. 1A). Because Gα i1 is denatured by the quench, the quantity of 32 P i measured in the assay reflects its rate of production rather than the rate at which ...
