Research Article | Molecular Biology and PhysiologyArchaeal Chromatin Proteins Cren7 and Sul7d Compact DNA by Bending and BridgingA long-standing question is how chromosomal DNA is packaged in Crenarchaeota, a major group of archaea, which synthesize large amounts of unique small DNA-binding proteins but in general contain no archaeal histones. In the present work, we tested our hypothesis that the two well-studied crenarchaeal chromatin proteins Cren7 and Sul7d compact DNA by both DNA bending and bridging. We show that the two proteins are capable of compacting...
Research Article | Molecular Biology and PhysiologySpecies-Specific Recognition of Sulfolobales Mediated by UV-Inducible Pili and S-Layer Glycosylation PatternsType IV pili can be found on the cell surface of many archaea and bacteria where they play important roles in different processes. The UV-inducible pili system of Sulfolobales (Ups) pili from the crenarchaeal Sulfolobales species are essential in establishing species-specific mating partners, thereby assisting in genome stability. With this work, we show that different Sulfolobus species have specific regions...
