Characterization of labeling sites on CarD. (A) Sites on CarD which were selected for site-specific mutagenesis and subsequent labeling with BODIPY-FL (colors correspond with binding isotherms in (B). (B) Binding isotherms for CarD mutants labeled with BODIPY-FL (note: several differences in this assay are as follows: 50 mM KGlu. 0.001% Triton X-100, and 12.5 nM CarD-BODIPY-FL were used in this experiment). (C) Summary of isotherm parameters for each CarD variant as well as domain interaction on the RPo where the BODIPY-FL probe is located.
