WEEKLY EPFL BIOE TALKS SERIES
Abstract:
In most bacteria, cell division depends on the tubulin homolog FtsZ and other proteins that form a large complex termed the divisome. This complex is composed of many proteins that together ensure proper execution of cell division resulting in two daughter cells of the same size and DNA content. Many archaea employ FtsZ homologs for cell division, but beside these homologs and the FtsZ membrane anchor SepF no other proteins being part of their cell division system have been identified.
Here, we demonstrate that three homologous proteins, all composed of a single conserved protein domain, partially play important roles in cell division in the euryarchaeon Haloferax volcanii. These proteins were identified by immunoprecipitation experiments and are from now on termed CdpB1-3 (cell division protein B). I will discuss the roles of the CdpB proteins during cell division in haloarchaea.
