FtsZ assembles the cytoskeletal scaffold of the Z ring that, along with additional proteins, constricts to divide the cell in two. (is, are). On the other hand, quinuclidine-treated cells were remarkably elongated with lengths in the range of 1050m (Figure 3a). "Another approach involves looking for other proteins that could be inhibited, and looking for existing inhibitors to make into drugs. What hypotheses can you come up with to answer the experimental question? Given the importance of FtsZ assembly in cell division, it has been suggested as a putative antibacterial drug target, due to its evolutionary distance from Biol. FtsZ inhibitors (including peptides, natural compounds, and other synthetic small molecules) can perturb the assembly dynamics of FtsZ by different mechanisms of action: (i) inhibition of FtsZ assembly and Z-ring formation (such as cinnamaldehyde, berberine, and totarol); (ii) disturbing cytokinesis by promoting or interrupting FtsZ . Ten microliter of sample mixtures were placed on a microscopic slide pre-treated with 0.1% (w/v) poly-L-lysine. Han H, Wang Z, Li T, Teng D, Mao R, Hao Y, Yang N, Wang X, Wang J. FEBS J. When bacteria become resistant to an antibiotic, it means that the antibiotic can no longer kill that bacteria.
