(A) Data from quantitative LacZ assays of four overlapping regions of 200 amino acids each of PBP1 tested for interaction with the C-terminal 123 amino acids of RipA. The C-terminal 259 amino acids of
The dissociation constants (Kd) of AZ-ODC and AZ-AZI were derived from global fitting of the sedimentation velocity data to the model of A+B↔AB hetero-association in the SEDTHAT program.
