A culture of E. coli JM109 WM647 containing the IPTG-inducible plasmid for the overexpression of green fluorescent protein-tagged FtsZ was grown in LB medium supplemented with 30gml1 of chloramphenicol. Inhibition of FtsZ assembly restrains the cell-division complex known as divisome, which results in filamentation, leading to lysis of the cell. Further in vitro studies suggest that prevention of FtsZ protofilament formation by quinuclidine 1 impairs the formation of Z-ring, and thus inhibits bacterial division. FtsZ proteins assemble into a ring that pinches the cell in two. The susceptibility antibacterial test also showed that there is no difference in the antibacterial potency of quinuclidine 1 against antibiotic-susceptible and antibiotic-resistant strains of E. faecium and S. aureus, thus confirming that the activity of the compound is not affected by common mechanisms of antibiotic resistance. FtsZ is a drug molecule that inhibits the possible target FtsZ which is known to be involved in cell division while imipenem is an antibio View the full answer Transcribed image text: What other -lactam antibiotics and inhibitors can be used in conjunction to limit colony growth?
