Role of cyclic nucleotides in Haloferax volcanii
Euryarchaeal genomes encode di-adeylate cyclases (DacZ). We showed that H. volcanii produces c-di-AMP and that under the tested...
Chemotaxis and localization of the archaellum in Haloferax volcanii
Although archaea use a totally different motility machinery than bacteria, eg. euryarchaea have obtained the full chemotaxis system from...
Motility in Archaea- the Archaellum
Archaea use a unique structure for swimming motility which is not hoomologous to bacterial flagella, but instead resembles type IV pili....
The UV induced pili system and DNA transfer
Almost all Sulfolobales contain an type IV pili operon named the UV inducible pilus operon (ups). This operon is highly induced after UV...
Regulation of archaellum expression in Sulfolobus acidocaldarius
Already in 2007 Zalan Szabo showed that archaellum expression in Sulfolobus solfataricus is starvation induced. Lateron we showed that...
Biofilm formation in Archaea
We studied how different Sulfolobus species form biofilms, how these are build and which components build their matrix. Moreover, we...
N-glycosylation in Sulfolobus acidocaldarius
Almost all extracellular proteins of archaea are modified by either N- or O-glycosylation or both. We have set out to analyze the...
