The effect of fusidic acid on the GTPase activity of <i>P. aeruginosa</i> EF-G1A and EF-G1B.

<p>Representative GTPase assays of the activity of EF-G1A and EF-G1B in increasing amounts of fusidic acid. The concentration of EF-G1A and EF-G1B were 1.0 and 0.3 μM, respectively, and the concentration of ribosomes was 0.4 μM. FA was added to the assay in concentrations from 4 μM to 250 μM. EF-G1A and EF-G1B are represented by filled diamonds (♦) and squares (■), respectively.
