The research in my laboratory is aimed at:
- elucidating the molecular machinery responsible for cell division in bacteria and
- determination of the temporal and spatial regulatory mechanisms necessary to ensure that the septum is placed at midcell and that newborn cells each receive a copy of the chromosome. Our work with the bacterium E. coli has led to the discovery of a cytoskeletel element, the Z ring, that directs septation in all prokaryotic organisms. The Z ring is formed by the self assembly of FtsZ, the ancestral homologue of tubulin.
Our present work involves:
- characterization of FtsZ assembly in vitro;
- mechanisms involved in positioning the Z ring at the division site; and
- determination of assembly pathways for other cell division proteins that are localized to the division site.
