Redesign of RGS18 gain-of-function mutants. (a) Sequences of RGS16, RGS18 and its mutants, color-coded as in Figure 4a. (b) Positions of the three RGS18 sites that were mutated in the redesign experiments, visualized as in Figure 4b. Corresponding RGS18 residue numbers are in parentheses. (c) GAP activities of the redesigned RGS18 mutants compared to activities of wild-type proteins. kgap values were determined as in Figure 4c.
