Bacterial Cell Division: Discovering how it begins and the network of protein interactions it requires. All cells must coordinate cell division with chromosome replication to ensure that the DNA is partitioned equally into newborn cells. We will establish the defect of a novel mutant blocked in the earliest stage of cell division in bacteria to obtain unique information about this vital regulatory step. We will use our newly discovered protein interaction network to establish what role protein i ....Bacterial Cell Division: Discovering how it begins and the network of protein interactions it requires. All cells must coordinate cell division with chromosome replication to ensure that the DNA is partitioned equally into newborn cells. We will establish the defect of a novel mutant blocked in the earliest stage of cell division in bacteria to obtain unique information about this vital regulatory step. We will use our newly discovered protein interaction network to establish what role protein interactions play in integrating cell division with other biological pathways in the cell to ensure its tight regulation. Our discoveries will facilitate the design of new antibiotics that target cell division to fight antibiotic-resistant bacteria and bioterrorism organisms.Read moreRead less
Establishing how bacterial cells position the division site. Cell division is essential for life. It is required for bacterial infections and, if uncontrolled, causes diseases such as cancer. We will establish how bacterial cells position the division site precisely to ensure faithful production of newborn cells. We will use the latest technology in bacterial cell biology to provide novel, clear-cut information to maintain Australia at the leading edge of this important area of research. There i ....Establishing how bacterial cells position the division site. Cell division is essential for life. It is required for bacterial infections and, if uncontrolled, causes diseases such as cancer. We will establish how bacterial cells position the division site precisely to ensure faithful production of newborn cells. We will use the latest technology in bacterial cell biology to provide novel, clear-cut information to maintain Australia at the leading edge of this important area of research. There is an alarming increase in antibiotic resistant bacteria and an imminent threat of bioterrorism. This research allows the opportunity for the development of new antibiotics to protect Australia protected from these dangerous bacteria. Read moreRead less
Regulating the earliest step in bacterial cell division: Z ring assembly. Cell division is essential for survival. What are the cues that signal cells to divide at the right place and at the right time? How do cells ensure that when division occurs to produce two newborn cells, each one receives the correct amount of DNA? The answers to these questions are essential to understand how organisms reproduce and grow. But they remain unknown. This research addresses these questions in bacteria. Our d ....Regulating the earliest step in bacterial cell division: Z ring assembly. Cell division is essential for survival. What are the cues that signal cells to divide at the right place and at the right time? How do cells ensure that when division occurs to produce two newborn cells, each one receives the correct amount of DNA? The answers to these questions are essential to understand how organisms reproduce and grow. But they remain unknown. This research addresses these questions in bacteria. Our discoveries will have a significant impact on our understanding of the regulation of this vital process and will facilitate the design of novel antibiotics that target it.Read moreRead less
Bacterial Proteomics: From Cell Division to Novel Antibiotic Targets. When a cell divides it is essential that each newborn cell gets a complete copy of the DNA. To ensure that this happens, cell division must be tightly controlled. It is not known how this occurs in bacteria. However, if we knew what molecules were involved in this control, we could target them to kill harmful bacteria. This project aims to identify such regulatory molecules as candidate targets for antimicrobial agents, with a ....Bacterial Proteomics: From Cell Division to Novel Antibiotic Targets. When a cell divides it is essential that each newborn cell gets a complete copy of the DNA. To ensure that this happens, cell division must be tightly controlled. It is not known how this occurs in bacteria. However, if we knew what molecules were involved in this control, we could target them to kill harmful bacteria. This project aims to identify such regulatory molecules as candidate targets for antimicrobial agents, with a view to developing powerful, novel antibiotics to protect us from the imminent threat of bioterrorism and antibiotic-resistant bacteria.
