Vancomycin inhibits cell wall biosynthesis by targeting the d-Ala-d-Ala terminus of peptidoglycan (PG). Inhibition of FtsZ assembly restrains the cell-division complex known as divisome, which results in filamentation, leading to lysis of the cell. It plays a virtual role in prokaryotic cell division. Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. There seem to be two types of bacteria that are not that effective but they become extremely effective when they are put together. It is well known that the amino-acid sequence of FtsZ is highly conserved in a wide range of bacteria.24 Alignment of the GTP-binding sites of FtsZ from various bacterial strains shows differences with pairwise root-mean-square deviation <0.8.14 The broad-spectrum antibacterial activity of quinuclidine 1 may be attributed to the highly conserved GTP-binding site of FtsZ. 8.
