Figure 8

Modeled interactions of the PA1113 ABC transporter with carbenicillin (light blue), verapamil (yellow), dibenzothiophene (green), and ATP (red). (A–D) show the general views of the binding of the PA1113 gene product to carbenicillin, verapamil, dibenzothiophene, and ATP, respectively. Detailed views of the binding site showing the principal amino acids potentially involved in the binding of carbenicillin, verapamil, dibenzothiophene, and ATP; ARG421, PHE423, ALA424 and LEU425 are implicated in binding with the different substrates.
