Each mutant is specified by name (first column) and position (second column, corresponding to S6 coordinate in Fig. 1 A). Parameters are as defined in Table I. VDI and CDI metrics are mean ± SEM. The final column indicates the figure in which the data are plotted (Figs. 4 A, 4 B, or 5 B), followed by the corresponding zone (i, ii, or iii) in Fig. 5 C.
