For example, synergy between quinuclidine 1 and ampicillin was tested against ampicillin-resistant S. aureus in the concentration range of 1.524gml1 (1/8 MIC to 1 MIC). FtsZ is found in almost all bacteria, many archaea, all chloroplasts and some mitochondria, where it is essential for cell division. (is, are). 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 eukaryotic tubulin. Payne, D. J. Microbiology. In the absence of quinuclidine 1, E. coli cells had integral Z-rings that consist of green fluorescent protein-tagged FtsZ. FtsZ inhibitor and Imipenem on their own are not highly effective as the number of colonies were still large in comparison to the control. 7. J. Biol. What hypotheses can you come up with to answer the experimental question? Pellentesque dapibus efficitur laoreet. We demonstrate that the FtsZ-specific inhibitor PC190723 acts synergistically with -lactam antibiotics in vitro and in vivo and that this combination is efficacious in a murine model of MRSA infection. FtsZ has a filament-forming GTPase and a structural homologue of eukaryotic tubulin. This is because of mutations in the bacterial genome that could cause structural changes which would cause the antibiotic to be essentially useless.
