Flavodoxin residues that change in chemical shift on titration with flavodoxin reductase and the AdoMet-binding domain of methionine synthase. Changes in average amide chemical shifts (Δδavg) of flavodoxin on titration with flavodoxin reductase (A) and the AdoMet-binding domain of methionine synthase in the absence and presence of AdoMet (B and C, respectively) are mapped onto the sequence of flavodoxin. The molar ratio of flavodoxin reductase: flavodoxin is 2.25:1 (A). The molar ratio of AdoMet-binding domain of methionine synthase:flavodoxin is 11.33:1 (B and C). The vertical color strips categorize the changes in average amide chemical shifts into high, medium, and low groups for projection onto the three-dimensional structure of flavodoxin in Fig. 3.
