Transmission electron micrographs of FtsZ in the presence of (A) GTP, and (B) GTP and chrysophaentin A. (A) Polymerization of recombinant E. coli FtsZ was induced with addition of GTP for 5 min at rt before transferring to a carbon grid, staining with 3% uranyl acetate, and visualizing by TEM, 44 000 x. (B) Incubation of FtsZ with 1 (50 μM) prior to addition of GTP inhibits polymerization and protofilament formation. No filaments were observed over the entire grid shown in panel B.
