nanomol

— These data demonstrated that PfG from Plasmodium has Ras-like GTPase properties rather than kinetic characteristics of a canonical G-protein: i) Although the determined Km value for BODIPY FL GTPγS 1.77 ± 0.36 nmol is in the nanomol range, the affinity for binding a fluorophoric GTP analogue is low compared to the human Gα 0 and G αi1 subunits with a Km of 14±8 nmol and 87±22 nmol, respectively ii) PfG from Plasmodium hydrolyses GTP rather quickly.
