FIG. 1.
Cation-dependent ATPase activities of different KdpFABC-His10 variants. KdpFABC-His10 (wild type) (A), G345A mutant (B), G345D mutant (C), G345S mutant (D), G470S mutant (E), S471G mutant (F). KdpFABC-His10 variants were purified and ATPase activity assays were performed as described previously (18).
