Extended Data Fig. 3: Fit coefficients for mutations in the active site of the ChlH protein with respect to [D_IX].

Data from Fig. 3 panels d, and e, is described by equation 5 unless stated otherwise, errors reported as one standard deviation of the fit coefficient. n.d. no activity detected. * these residues are adjacent to site 1. ^† Fitted to the Hill equation (6), where s_0.5 is reported instead of K_M, and k_cat/s_0.5 instead of k_cat/K_M. Fitted to the substrate inhibition equation (7), where K_i = 37.1 ± 7.7 μM.
