Interaction network between the periplasmic domains of the P. aeruginosa Xcp secreton and substrates by SPR. Ligand and analytes are indicated following the code used under “Experimental Procedures.” Positive interactions are indicated by black boxes, in which the Kd values (μm) of the interactions are indicated. Gray boxes with dashes indicate that no interaction was detected. The schemes for all positive interactions are represented below the table and follow the color code used in Fig. 1. Pp, pseudopilus; ND, not determined.
